A contact type IC card (1) includes a plurality of holes (14) formed in the second portion of a core sheet providing a card body (8). The second portion is other than a first portion including a mounting portion that has an IC module (10) mounted therein. When the card body (8) is bent, the holes (14) serve as rigidity adjusting means for preventing bending stress from occurring in the IC module (10). |
