摘要： A smart card comprises an IC module and an antenna for non-contact transmission. The IC module has both a contact-type function and a non-contact-type function. In the contact-type function, power reception and signal transmission/reception is effected via an electrical contact. In the non-contact-type function, power reception and signal transmission/reception is effected in a non-contact state by an electromagnetic coupling system without providing the IC card with an electrical contact. The IC module and the antenna comprise first and second coupler coils, respectively, which are disposed to be closely coupled to each other, and the IC module and the antenna are coupled in a non-contact state by transformer coupling. An antenna coil is disposed so as not to overlap an engagement portion for the IC module, which is a region of an external terminal electrode serving as a contact-type electrode, an embossing region, or a magnetic stripe region.
