PROBLEM TO BE SOLVED: To provide a method for manufacturing a touch pad, and a touch pad, in which complication in works of manufacturing is prevented, materials can be reduced, and burrs can be easily removed.SOLUTION: The method for manufacturing a touch pad aims manufacturing a touch pad which includes an insulating base film 1 and a conductive pattern layer 6 formed on the surface of the base film 1 and having a plurality of conductive parts such as electrodes spaced and arrayed in XY directions. The method comprises: depositing a resist layer on the base film 1; exposing the resist layer through a mask and developing to form a resist pattern layer; forming a metal thin film over the base film 1 and the resist pattern layer; removing the resist pattern layer with a part of the layered metal thin film to form a pattern in a residue of the metal thin film to form the conductive pattern layer 6; and dry-etching the conductive pattern layer 6 on the base film 1. As burrs in the conductive pattern layer 6 are removed by dry etching, formation of an overhang part for preventing burrs is unnecessary. |
