In inlets used for ID tags and the like, a defective connection between an integrated circuit part and an antenna is suppressed by improvement of tolerance for a bending or a pressing pressure. The integrated circuit part includes a semiconductor chip and a multilayer substrate having a concave portion. The semiconductor chip is mounted on the bottom of the concave portion. The multilayer substrate includes a connection electrode at the top surface and a connection electrode connected to the semiconductor chip on the bottom of the concave portion. The connection electrode on the bottom of the concave portion is connected to the connection electrode at the top surface by a penetration electrode inside a multilayer substrate. By such a configuration, the semiconductor chip is connected to the antenna.
