ELECTROCONDUCTIVE MEMBER FOR NON-CONTACT TYPE DATA CARRIER, AND PRODUCTION METHOD AND DEVICE THEREFOR

PROBLEM TO BE SOLVED: To easily and rapidly form a bridge of an electroconductive member for a non-contact type data carrier. SOLUTION: The method includes: layering an insulating strip-like base material 10a and the electroconductive strip having the same width as the bridge 14 to connect the terminal parts of each the antenna thereon and having a thermoplastic adhesive layer so as to be aligned in the terminal parts; bonding a portion connecting the antenna terminals on the conductive strip 14a onto the base material as the bridge through the thermoplastic adhesive layer; temporarily fixing a portion between the terminal parts of the adjacent antennas on the electroconductive strip to the base material as an unnecessary part 14b through the thermoplastic adhesive layer; removing the unnecessary part from the electroconductive strip at a boundary with the bridge; and peeling the unnecessary part temporarily fixed to the base material from the base material. Because it is not necessary to punch out the bridge from wide metal foil, the unnecessary parts of the metal foil are reduced. Because the bridge is formed by cutting the electroconductive strip on both the sides of the pair of the terminal parts, wire breakage of an electroconductive part 13a is prevented.
