CPC Code(s):
Abstract: a material sheet is provided having antenna patterns that include first and second coupling portions that are transported toward a mounting position, and an adhesive member that is disposed on the material sheet before reaching the mounting position. at a pickup position, a mounting device picks up an rfic module including an rfic chip and first and second terminal electrodes connected to the rfic chip. at the mounting position, the mounting device mounts the picked-up rfic module onto the adhesive member on the material sheet so that the first coupling portion and the first terminal electrode face each other and so that the second coupling portion and the second terminal electrode face each other.
