Claim 11:
12. A wireless communication device manufacturing apparatus comprising:
a transporting device configured to transport a material sheet containing one surface having at least one antenna pattern including first and second coupling portions towards a mounting position;
an applying device configured to apply an adhesive member having a stickiness to the one surface of the material sheet before the material sheet reaches the mounting position;
a mounting device configured to:
pick up, at a pickup position, a radio-frequency integrated circuit (RFIC) module including an RFIC chip and first and second terminal electrodes connected to the RFIC chip, and
mount, at the mounting position, the picked-up RFIC module onto the adhesive member on the material sheet at a position where the first coupling portion faces the first terminal electrode and the second coupling portion faces the second terminal electrode; and

a recovery reel having a winding shaft with a radius R and being configured to wind up the material sheet having the picked-up RFIC module mounted at the mounting position with the other surface of the material sheet contacting the picked-up RFIC module mounted on the adhesive member on the one surface of the material sheet,
wherein the applying device is configured to apply the adhesive member to the material sheet, before the mounting device mounts the picked-up RFIC module onto the adhesive member, to have a protrusion amount B that protrudes past each side of the RFIC module in a winding direction of the recovery reel when the picked-up RFIC module is mounted onto the adhesive member, with the protrusion amount B satisfying Equation 1:, B
