Abstract: An electromagnetic-coupling dual IC card includes an IC module and a plate-like card body. The IC module includes a module substrate having a first surface and a second surface, contact terminals provided on the first surface of the module substrate to be contactable with an external contact-type device, an IC chip having a contact communication function and a contactless communication function and disposed on the second surface, and a first connecting coil provided on the first surface. The plate-like card body includes an antenna sheet embedded therein and has a recess for holding the IC module, the antenna sheet being provided with a coupling coil to be electromagnetically coupled to the first connecting coil, and a main coil connected to the coupling coil to perform contactless communication with an external contactless-type device. The first connecting coil does not overlap with the contact terminals in plan view.
