Dual ic card

A dual IC card comprising:

• an IC module including a contact terminal portion contacting an external machine, a connecting coil configuring a contactless terminal portion by electromagnetic coupling, and an IC chip having a contact communication function and a contactless communication function;
• an antenna including a coupling coil portion for electromagnetically coupling with the connecting coil of the IC module, and a main coil portion connected to the coupling coil portion to perform contactless communication with the external machine;
• and
• a plate-like card body in which the antenna is arranged and a recess is formed for accommodation of the IC module, wherein:
• the coupling coil portion is located at a position outside the recess of the card body when viewed from an opening side of the recess.
