A method for manufacturing an antenna sheet. The method is for connecting at least one of an antenna coil and a connection pattern, to a conductive member. The at least one of the antenna coil and the connection pattern is provided on one surface of a substrate and the conductive member is provided on the other surface of the substrate. The method includes a pressing process performed to form a first through hole to the substrate, wherein the first through hole passes through the substrate, and to bring the at least one of the antenna coil and the connection pattern, and the conductive member into contact with each other. The method also includes a melting process performed to melt the at least one of the antenna coil and the connection pattern, and the conductive member to each other.
