Conventionally, an IC card in which an integrated circuit is built in a card substrate is formed into a standard 54 mm long and 86 mm wide dimension similar to a commonly used credit card, and a plurality of (8 Are provided, and data can be read and written by the card reader / writer via the contacts. This type of IC card is a contact-type card. However, in recent years, a non-contact type IC card capable of reading and writing data using an induction electromagnetic field as a transmission medium has been developed. A system that opens and closes a gate simply by holding a writer and holding a non-contact IC card is also being studied. On the other hand, portable electronic devices such as cellular phones are becoming lighter and smaller and can transmit and receive data as well as voice communications, and are widely used by many people. When an IC card is mounted on such a cellular phone or the like, it is large if it has the same shape and dimension as a conventional credit card. For this reason, for example, a small electronic card formed to have a shape dimension of about 20 mm in length and 25 mm in width. The use of (micro card: IC chip) has been studied.
