A membrane switch includes an upper electrode sheet that includes an upper electrode, a lower electrode sheet that includes a lower electrode facing the upper electrode, and an adhesive layer that joins the upper electrode sheet to the lower electrode sheet; and the upper and lower electrodes come into contact with each other due to a pressing force, which is applied to at least one of the upper electrode sheet and the lower electrode sheet, and conduct electricity. The upper electrode sheet includes: an upper base on which the upper electrode is formed; and an upper insulating layer that is provided between the upper base and the lower electrode sheet, includes a first opening at a position corresponding to the upper electrode, and is joined to the lower electrode sheet by the adhesive layer.
