Antenna sheet, data carrier with non-contact IC, and method for manufacturing antenna sheet

摘要

A method for manufacturing an antenna sheet, includes: a pressing step in which an overlapped portion of an antenna coil and/or a connection pattern formed from a metal material and provided on one surface of a substrate formed from a thermoplastic resin, and a conductive member formed from a metal material and provided on the other surface of the substrate is pressed using a pressing unit at least from the surface of one side of the substrate; and a welding steps in which the overlapped portion of the antenna coil and/or the connection pattern and the conductive member is welded.

主权项

1. An antenna sheet comprising:
a substrate; a band-shaped antenna coil formed on one surface of the substrate; a connection pattern formed on the one surface of the substrate; a conductive member provided so as to extend on another surface of the substrate in a direction that intersects with the antenna coil, and to overlap, in view of a plane of the substrate, with at least one end part of the two end parts of the antenna coil; and a melted part formed at an overlapped portion, the overlapped portion being a portion where the at least one of the antenna coil and the connection pattern, and the conductive member overlap each other, wherein the conductive member and the at least one of the antenna coil and connection pattern are melted in the melted part, the conductive member is formed from a first metal material, the at least one of the antenna coil and the connection pattern is formed from a second metal material, and the melted part consists of the first metal material and the second metal material.
