1. A method for manufacturing a wireless communication device, the method comprising:
transporting a material sheet containing one surface having at least one antenna pattern, which includes first and second coupling portions, towards a mounting position;
applying an adhesive member having a stickiness to the one surface of the material sheet before the material sheet reaches the mounting position;
picking up, by a mounting device, a radio-frequency integrated circuit (RFIC) module that includes an RFIC chip and first and second terminal electrodes connected to the RFIC chip, at a pickup position;
mounting, by the mounting device, the picked-up RFIC module onto the adhesive member on the material sheet at the mounting position where the first coupling portion faces the first terminal electrode and the second coupling portion faces the second terminal electrode; and
winding up, by a recovery reel having a winding shaft with a radius R, 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 adhesive member is applied 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
