A dual IC card with an IC chip having both a contact-type transmission function and a contactless-type transmission function, and a module substrate having an external terminal, which is a contact-type transmission portion, and a connecting coil, which is a contactless-type transmission portion; an antenna sheet including an antenna substrate having first and second surfaces, a coupling coil having a second surface coil provided on a second surface of the antenna substrate, the coupling coil configured to be electromagnetically coupled to the connecting coil, and an antenna coil connected to the coupling coil for contactless communication with an external device; and a card body in a plate-shape housing the antenna sheet and with a recess for the IC module, with at least a part of the second surface coil positioned inside the recess when viewed in a thickness direction.
