PROBLEM TO BE SOLVED: To provide a contact structure for a push switch, which has a simple structure and low switching resistance. SOLUTION: The push switch is equipped with: a cylindrical center boss part 20 integrally provided on the back side of a pressing part 14 formed so that it can be depressed; a bent part 16 concentrically formed in a dome shape around the pressing part 14; and a conductor part 22 provided on the end surface of the center boss part 20. The pattern of a contact 26 connected to the conductor 22 is formed in the shape of the teeth of a comb and a pair of electrodes face each other on the surface of a circuit board 24. When the diameter of the conductor part 22 is almost even number times as long as the sum of the pattern width of the contact 26 and a gap, the center of the conductor 22 is aligned with the center of the pattern of the contact 26. When the diameter of the conductor part 22 is almost odd number times as long as the sum of the pattern width of the contact 26 and the gap, the center of the conductor is aligned with the gap center of the pattern of the contact 26.
