Abstract
The present invention provides a radio frequency identification (RFID) tag which exchanges information with an external device in a noncontact manner, in which a paste is used as a material for an antenna, and which is designed to avoid the problem due to swelling of the paste caused by a pressing force from bumps of an IC chip. A paste escape recess is provided in which part of the paste provided to form the antenna is caused to flow therein by the pressure received from the bumps when the IC chip with the bumps is connected to the antenna.
