In recent years,
A non-contact type IC card that can read and write data using an induction electromagnetic field as a transmission medium has been developed. For example, a system in which a card reader / writer is provided at an entrance / exit gate and the gate is opened and closed simply by holding the non-contact type IC card over the gate. Are also being studied. On the other hand, portable electronic devices such as mobile phones have become increasingly lighter and smaller, and have become capable of transmitting and receiving data as well as voice communication. When an IC card is attached to such a mobile phone or the like, for example, the height is 20 mm and the width is 25 m.
The use of a small electronic card (micro card) formed in a shape and dimension of about m has been studied.

[0003]

A small electronic card (micro card) cannot be used alone because it does not have an antenna or the like, and is formed in a small shape and size of several tens of mm. Are lost or inconvenient to handle. Therefore, there is a demand for a small electronic card which can be used as a non-contact type IC card even before being mounted on a mobile phone, and which can be easily mounted on the mobile phone. Also, once this kind of small electronic card is once removed from a portable electronic device such as a mobile phone, it cannot be used alone as a non-contact IC card. There is a risk that the card becomes unusable and that many important information stored in the card cannot be easily used. Further, it is desired that the small electronic card can be manufactured at a low cost by simplifying the manufacturing process.

[0004] The present invention has been made in view of the above circumstances,
An object of the present invention is to provide an IC card which can be used as it is as a non-contact type IC card, can easily cut out a small electronic card which can be mounted on an antenna coil provided in a portable electronic device, and can be manufactured at low cost. .
