An RFID tag manufacturing apparatus that includes an antenna base material conveying part that conveys an antenna base material with antenna patterns in a first direction. Moreover, the apparatus includes a conveying part for an RFIC element that supplies an RFIC element having terminal electrodes for connection with the antenna patterns on one principal surface. A plotter is further provided that conveys the supplied RFIC element to a predetermined position of the antenna patterns and temporarily bonds the RFIC element to the antenna patterns. Finally, the apparatus includes a pressurizing part that applies a pressure to the temporarily bonded RFIC element to permanently bond the RFIC element to the antenna patterns. In an aspect, the plotter includes a fixed arm portion and a movable suction head.
