PROBLEM TO BE SOLVED: To provide a switch capable of improving reliability by reducing short circuit or a loose connection. SOLUTION: The switch 21 is structured with a surface panel 22 with a spacer having a movable side contact point 27, and a fixed side formation 23 having fixed side contact points 31 in opposition to the movable side contact point 27 with the surface panel 22 with a spacer laminated in retrofit. An upper part of a circuit pattern 29 connected to the fixed side contact points 31 is covered with an insulation layer 30 with the circuit pattern 29 in a buried state, and the surface of the insulation layer 30 is protruded to make up protrusions 34, on a tip face of which, the fixed side contact points 31 is arranged to structure the fixed side formation 23.
