1. A portable electronic device comprising:
- a card base having a holding recess;
an IC module having a substrate, a large scale integration (LSI) mounted on the substrate, a protection member which covers the LSI, the IC module being held in the holding recess from the protection member, a contact terminal provided on the substrate, and a connection member one end of which is electrically connected to the contact terminal and another end of which is electrically connected to the LSI to form a loop; and
an irregular surface defined by a projected portion, which is integral with the protection member, which is formed on a surface of the protection member, and which is made of the same material as the protection member, the irregular surface opposing an inner bottom of the holding recess when the IC module is held in the holding recess, and the projected portion covering the loop of the connection member.

Abstract
A portable electronic device includes a card base having a holding recess and an IC module having a substrate, an LSI mounted on the substrate, and a protection member which covers the LSI. The IC module is held in the holding recess from the protection member. The portable electronic device further includes a reinforcing projection that is formed along the circumference of the surface of the protection member which faces the inner bottom of the holding recess.

8. A portable electronic device comprising:
-
a card base having a first holding recess, a second holding recess formed in an inner bottom of the first holding recess, and an irregular portion formed in an inner bottom of the second holding recess; and an IC module having a substrate, a large scale integration (LSI) mounted on the substrate, a protection member which covers the LSI, an irregular surface defined by a projected portion, which is integral with the protection member, which is formed on a surface of the protection member, and which is made of the same material as the protection member, the protection member partly opposing the projected portion of the irregular portion formed in the inner bottom of the second holding recess when the substrate is held in the first holding recess and the protection member being inserted in the second holding recess, a contact terminal provided on the substrate, and a connection member one end of which is electrically connected to the contact terminal and another end of which is electrically connected to the LSI to form a loop, the projected portion covering the loop of the connection member. - View Dependent Claims (9, 10, 11)
