PROBLEM TO BE SOLVED: To improve the reliability in operation by applying constitution free from generating weld lines, and to simplify the assembling with a simple structure using the small number of components. SOLUTION: This illuminated push button switch includes a printed board 40 provided with a fixed contact and an emitter, a rubber switch 30 having integrally formed several push button switches respectively having a movable contact and a diffusion part, and a key top part 20, in a state that they are positioned and overlapped with each other. The key top part is manufactured by printing characters or the like onto a plastic film 21, and inserting and molding plural key tops by using a transparent resin such as an acryl resin. Accordingly, the constitution free from the generation of weld lines can be realized. Further the number of components can be reduced.
