Publication number: 20140036413Abstract: An electrochemical capacitor includes a casing, an electrolyte, a storage element, a wiring and an adhesive layer. The casing forms a liquid chamber. The electrolyte is housed in the liquid chamber. The storage element is a storage element in which a positive electrode sheet, a separator sheet and a negative electrode sheet are laminated, being housed in the liquid chamber. A capacitance formed between a positive electrode active material in the positive electrode sheet and the electrolyte is greater than a capacitance formed between a negative electrode active material in the negative electrode sheet and the electrolyte. The wiring is connected to the liquid chamber. The adhesive layer is made of a conductive adhesive made with a synthetic resin including conductive particles. The adhesive layer covers the wiring, causes the positive electrode sheet to adhere to the casing, and electrically connects the wiring with the positive electrode sheet.Type: ApplicationFiled: July 30, 2013Publication date: February 6, 2014Applicant: Taiyo Yuden Co., Ltd.Inventors: Naoto Hagiwara, Kyotaro Mano
