Abstract: A pressing operation body includes an inversion spring having a dome shape; and a rubber stem configured to bend in response to pressing and press the inversion spring. The inversion spring includes a dome portion, and a plurality of leg portions that are extended outward from an outer peripheral edge of the dome portion. The rubber stem includes a base portion configured to support a lower edge of the rubber stem. The base portion includes a plurality of retaining portions configured to retain the plurality of leg portions of the inversion spring.

Abstract: Provided is a laminated type energy device which can enhance the sealing ability and the adhesibility between the layered structure and the sealing body which houses the layered structure, and the degree of space-saving, and uses the sealing means with sufficient productivity and reliability. The laminated type energy device includes: at least two layers of layered structure 80 in which a positive electrode and a negative electrode are alternately laminated so that positive and negative extraction electrodes 32a and 32b are exposed, inserting a separator 30 in which an electrolysis solution and ion pass therethrough between positive and negative active material electrodes 10 and 12; laminate sheets 40a and 40b overlaid from front and back surfaces of the layered structure 80 to compressively seal the layered structure 80; and contact holes 20a and 20b for use in spot bonding of the laminated type energy device to a module substrate 100.
