PROBLEM TO BE SOLVED: To provide a push button structure evading failure in an electric part in a cover during an electrostatic surge testing without enlarging surrounding shape of a button, by having no occurrence of an operation failure in the button or degradation in appearance by easily aligning a center of an opening in the cover and a center of the button when assembling. SOLUTION: This push button includes a structure aligning the central position of the button 2 and the center of the opening 10, by having a second annular rib 11 surrounding the opening 10 on the inside surface of the cover enter into an inner side of a first annular rib 5 formed on a top surface of a flange 3 of the button 2, when a frame body 1 is attached while entering the button 2 into the opening 10 on the inner surface of the cover 9, and having each guide rib 6 come into contact with an outer periphery surface of the second annular rib 11.
