PROBLEM TO BE SOLVED: To obtain a crisp operation feel and improve keying characteristics and repetition durability required of push-button switch functions by enhancing the positional accuracy of a cover member for a push-button switch relative to a metallic coned disc spring, and reduce the manufacturing costs including the design cost of a circuit board. SOLUTION: In this cover member 4 for a push-button switch, a key top 2 is formed on the upper surface side of a cover base material 1 and a pressing projection 3 corresponding to the key top 2 is provided on the rear surface of the cover base material 1. With the top of a metallic coned disc spring 5 abutting on the center position of the pressing projection 3 of the cover member 4 for a push-button switch, the metallic coned disc spring 5 is adhesively stuck and fixed to the pressing projection 3 by means of an elastic adhesive-agent 6 having an elongation of 75 to 700% with its amount ranging from 2 to 7 mg.
