Patent ID: 7478473

Claim:
A method of manufacturing an IC card, comprising the steps of: (a) providing a wiring substrate having an external connecting terminal and wiring; (b) disposing a semiconductor chip over the wiring substrate and connecting the semiconductor chip electrically to the external connecting terminal through bonding wire; and (c) covering the wiring substrate and the semiconductor chip with a case in such a manner that the external connecting terminal of the wiring substrate is exposed, wherein the case has a first end side near which the external connecting terminal is disposed and a second end side positioned on an opposite side to the first end side, wherein a planar outline of the wiring substrate is smaller than half of a planar outline of the case, wherein the step (c) comprises a step of disposing the wiring substrate in an area of the case closer to the first end side with respect to a middle position between the first and the second end side, and wherein the step (c) further comprises the steps of (c1) allowing a movable switch to be held in an area of the case other than the area where the wiring substrate is disposed; (c2) providing a carrier; (c3) mounting the plural cases each holding the movable switch to the carrier; and (c4) accommodating the wiring substrate and the semiconductor chip in each of the plural cases on the carrier.
