Abstract: A switch includes: a first electrode sheet including a first electrode; a second electrode sheet including a second electrode that faces the first electrode sheet; and an adhesive that includes a first opening through which the first electrode faces the second electrode sheet and that attaches the first electrode sheet to the second electrode sheet. The first electrode sheet includes: a first substrate on which the first electrode is disposed; a first spacer between the first substrate and the second electrode sheet that includes a second opening at a position corresponding to the first electrode; and a first base between the first substrate and the first spacer that overlaps at least a portion of an edge of the first opening of the adhesive. The first spacer is attached to the second electrode sheet by the adhesive.

Abstract: 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. The upper insulating layer is formed on the upper base.

Abstract: An object of the present invention is to provide a laminate material for a transparent substrate material or protecting material, which exhibits excellent surface hardness, excellent form stability under heat or when absorbing water, and excellent adhesion to a coating composition, and excellent heat resistance under load, and which maintains excellent adhesion between the layers. The present invention is a laminate material comprising a first layer comprising a vinyl copolymer resin (A), and a second layer comprising a thermoplastic resin (B) stacked on the first layer, or comprising the first layer, the second layer, and a third layer comprising the vinyl copolymer resin (A) stacked on the second layer (the vinyl copolymer resin (A) constituting the first layer and the vinyl copolymer resin (A) constituting the third layer may be the same or different).
