PROBLEM TO BE SOLVED: To provide a manufacturing method for a key top sheet for a switch, in which no damage is given to a printed key symbol or the like at molding and the thinning of the key top sheet is contrived and further enough brightness can be ensured even under the state being used in an illumination type switch gear. SOLUTION: A key symbol 21d is printed on the rear surface of a thermoplastic resin film F. Next, in the film F, a key top outer shell part 21a swelling outwards to a front surface side is formed by means by vacuum forming or the like. Next, the film F is held horizontally under the state that its rear surface is directed vertically upwards so as to pour an ultraviolet curing resin P in the key top outer shell part 21a in order to cure the ultraviolet curing resin P, resulting in molding a key top solid part integral with the key top outer shell part 21a in the key top outer shell part 21a. |
