PROBLEM TO BE SOLVED: To lower the cost for forming a panel, and to simplify structure by providing a pressure transmitting member in an outer surface of a dome part of a click member for push button switch. SOLUTION: A click member 1 is formed with plural dome parts 3 projected from an upper surface of an elastomer resin sheet 2. An outer surface of a top of the dome part 3 is provided with a pressure transmitting member 4, and the operating pressure is applied to the top surface through a key top part. An inner surface of the dome part 3 is provided with a movable contact 5. This movable contact 5 is provided at a position, in which the movable contact 5 faces to a fixed contact provided in a base plate of a switch member when the click member 1 is assembled in a push button switch member, and when the dome part 3 is pushed, the movable contact and the fixed contact contact with each other for electrical continuity. This pressure transmitting member 4 is formed 50-300μm in thickness.
