constitutes, and appoints Robert L. Katz, Susan Wagner-Fleming, and
Kathryn L. Salo and each of them acting individually (each of the foregoing is
referred to as an Authorized Signer), as the Insiders true and lawful
attorney-in-fact, each with full power and authority to:
1. prepare, execute, and file on the Insiders behalf any and all Forms 3, 4
and 5 (including any amendments thereto), in accordance with Section 16(a)
of the Securities Exchange Act of 1934 (Exchange Act) and the rules
promulgated thereunder, that the Insider may be required to file with the
United States Securities and Exchange Commission as a result of the Insiders
ownership of, and transactions in, securities of Jabil Circuit, Inc.
the Company); and
2. do and perform any other actions of any type whatsoever that (i) may be
necessary, desirable or appropriate to prepare, execute, and file any such
Forms 3, 4, or 5 with the United States Securities and Exchange Commission
and any other governmental or private authority or entity, or (ii) in the
discretion of the Authorized Signer, may be of benefit to, in the best
interest of, or are necessary or appropriate for and on behalf of the
Insider in connection with any of the foregoing, it being understood that
the documents executed by such Authorized Signer on behalf of the Insider
pursuant to this Power of Attorney shall be in such form and shall contain
such terms and conditions as such Authorized Signatory may approve in such
Authorized Signatorys discretion.
	This Limited Power of Attorney revokes and replaces any earlier
dated power of attorney relating to the reporting obligations of the Insider
with regard to the Insiders ownership of, or transactions in, securities of
the Company under Section 16 of the Exchange Act and the rules promulgated
thereunder.  The power and authority of the Authorized Signers under this
Limited Power of Attorney shall continue until the Insider is no longer
required to file Forms 3, 4 and 5 with regard to the Insiders ownership of,
or transactions in, securities of the Company, unless earlier revoked by the
Insider in a signed writing delivered to the Authorized Signers.
The undersigned hereby grants to each such Authorized Signer full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and
powers herein granted, as fully to all intents and purposes as the
undersigned might or could do if personally present, with full power of
substitution or revocation, hereby ratifying and confirming all that such
attorneys-in-fact, or such attorneys-in-facts substitute or substitutes,
shall lawfully do or cause to be done by virtue of this power of attorney
and the rights and powers herein granted.
	The Insider acknowledges that:
1. this Limited Power of Attorney does not relieve the Insider from his or
her responsibilities to comply with the requirements of Section 16 of the
Exchange Act and the rules promulgated thereunder; and
2. neither the Company nor any Authorized Signer assumes (i) any liability
for the Insiders responsibilities to comply with the requirements of
Section 16 of the Exchange Act and the rules promulgated thereunder,
(ii) any liability of the Insider for any failure to comply with such
requirements, or (iii) any obligation or liability of the Insider for
disgorgement of profits under Section 16(b) of the Exchange Act.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney be
executed as of the date set forth below.
