PROBLEM TO BE SOLVED: To provide a push-button switch in which plating of the crown part of a contact spring is hardly peeled off. SOLUTION: The push-button switch is provided with an operating member 4, a fixed contact 9 provided on a substrate 7 opposed to this operating member 4, a contact spring 10 on the concave curved surface side of which crown part 11, a movable contact 12 corresponding to the fixed contact 9 is provided, and a sheet member 13 which is adhered to the convex curved surface side of the contact spring 10 and the substrate 7 and fixes the contact spring 10 to the substrate 7 reversibly and restorably. The movable contact 12 protrudes on the concave curved surface side of the crown part 11. A transmission member 16 for transmitting the pushing force given to the operating member 4 is arranged at the opposed position to the crown part 11 of the contact spring 10 interposing the sheet member 13, and is adhered to the sheet member 13. This transmission member 16 is established to be dimensions to cover a range wider than a plane of projection of a prescribed range of the crown part of the contact spring 10 including the movable contact 12.
