A method for forming an indicator portion (13, 55) on a push switch (10, 50) such as a pushbutton switch (10) or a membrane switch (50), the indicator portion being excellent in terms of design property and image quality and allowing fine picture patterns, designs, etc that are difficult to be reproduced with conventional printing systems to be represented with high resolution, and to provide a push switch (10, 50) having the indicator portion. In order to form the indicator portion (13, 55), in which a color design image such as a letter, a pattern, design etc is indicated, on the push switch (10, 50), there are performed the following steps of: forming a colorant layer (18, 59) by printing a color design image on a base sheet (19, 58) by a printer; transferring the colorant layer (18, 59) to a transfer resin (12, 53) through an adhesive (15, 54), the transfer resin constituting a surface of the push switch (10, 50); and forming the indicator layer (13, 55) on the transfer resin (12, 53) by peeling off the base sheet (19, 58) and using the colorant layer (18, 59) as the indicator layer (13, 55).
