Abstract
The object of the present invention is to provide a method of manufacturing a metallic switch with high productivity. A transparent printed layer (4) is patterned and formed on a metalizing layer (3) formed on the front surface of a transfer substrate, and the metalizing layer (3) is subjected to etching. The metalizing layer (3) and the transparent printed layer (4) are integrally transferred onto a key top body (6). As a result, the metalizing layer, which has a low strength and can be easily fractured, is protected and reinforced by the transparent printed layer (4), the metalizing layer can be transferred with high stability, and a metallic switch is manufactured in an easy manner and with good efficiency.
