Abstract: A push button capable of improving shock resistance and a timepiece equipped therewith are provided. This push button includes an operation member having a shaft section inserted into a through hole of a case and a head section provided on the outer end of the shaft section, and an elastic member which presses the head section toward the outside of the case or is elastically deformed, and this elastic member includes a buffer section that buffers a pressure externally applied to the head section which is greater than a predetermined pressure. Accordingly, when a pressure greater than the predetermined pressure is applied to the head section, the head section comes in contact with the buffer section while elastically deforming the elastic member so as to buffer the pressure. By this structure, shock resistance is improved.
