Abstract
An IC card includes a metal plate having a through hole penetrating therethrough in one direction, a metal support member disposed inside the through hole and separated from the metal plate, and an IC module supported inside the through hole by the support member. The support member has a cavity penetrating therethrough in the one direction and accommodating a part of the IC module and a slit extending from the cavity to a periphery thereof.
Claims20
An IC card comprising:
- a metal plate having a first through hole penetrating therethrough in a thickness direction;
- a metal support member disposed at least partially inside the first through hole and spaced apart from the metal plate without contacting the metal plate;
- and
- an IC module supported inside the first through hole by the metal support member,
- wherein the metal support member has a cavity penetrating therethrough in a thickness direction and accommodating a part of the IC module and a slit extending from the cavity to a periphery thereof.
