RFID tag manufacturing methods and RFID tags

摘要

A method of manufacturing an RFID tag includes a step of preparing a strap (120) having a connecting metal pattern (122) formed on a base (121), and mounted with a circuit chip (11), the pattern connecting the circuit chip to a metal antenna pattern (132). A substrate (130) has a concave section (133) which houses the circuit chip and is formed on a first face. The metal antenna pattern (132) extends over a first face and a second face of a base (131) so as to circle them except for the concave section and to have the two ends positioned across the concave section. The method includes a connection step of positioning and directing the strap and the substrate to house the circuit chip in the concave section and covering the strap and the substrate with a covering material (140) so as to fix the strap and the substrate in a state where the connection metal pattern is connected to the metal antenna pattern.
