A first invention relates to an IC card (1) provided with a card base (3) having the front and back sides; electromagnetic stripes (7) arranged on the back side of the substrate, and capable of storing information; and a module (5) incorporating a semiconductor circuit device having connecting terminals (5-1) arranged on a given area on the front side of the base (3) so as to connect the card (1) with external equipement, wherein the end (5a) of the module (5) is arranged in the direction perpendicular to the electromagnetic stripes (7). With the structure described above, it is possible to reduce the step on the base (3) in the vicinity of the upper part of the module (5), thus relaxing the stress exerted on this part. Further, according to a second invention, the card (1) has a structure such that the end (5b) gradually becomes thinner. The step in the vicinity of the upper part of the module (5) is further smaller, so that the stress exerted on the part is relaxed. Furthermore, according to a third invention, a part of the end (5b) has a cuspidated shape, and the module (5) is so shaped that the leading end (5c) of the end (5b) is cuspidal. Hence, the step in the vicinity of the upper part of the base (3) is smaller, thus enabling the stress exerted on the part to be relaxed. The invention provides an IC card having a high durability. |
