PROBLEM TO BE SOLVED: To provide a membrane switch which can obtain a stable input characteristic.SOLUTION: A membrane switch 11 includes: a spacer 2 having an opening 20; and a first sheet 3 having a first electrode 31, disposed in a manner to correspond to the opening 20, and disposed on one principal plane side of the spacer 2; and a second sheet 4 having a second electrode 41, disposed in a manner to face the first electrode 31 through the opening 20, and disposed on another principal plane side of the spacer 2. In a planar shape, the first electrode 31 includes a linear shaped part 312 and a linear shaped part 313, and further, the first sheet 3 includes a plurality of dot spacers 35 disposed in positions between the linear shaped part 312 and the linear shaped part 313.SELECTED DRAWING: Figure 1 |
