    摘要: A method of manufacturing a key top for a push-button switch (7,14,19,23,24,25) according to the present invention includes forming a hot-melt adhesive layer (3,11,16) on a resin key top (4) so as to have a shape corresponding to a display portion (5) for displaying a letter, symbol, or other indicia, and transferring a metallic thin film layer (2,12,17) onto the hot-melt adhesive layer (3,11,16). Therefore, the metallic thin film layer (2,12,17) is not damaged due to coating of the hot-melt adhesive layer (3,11,16), and positioning of the display portion (5) is unnecessary. Further, when a transfer resin layer is formed on the metallic thin film layer (2,12,17), oxidation of the metallic thin film layer (2,12,17) or damages thereto can be prevented.
