Abstract
An electrochemical device includes an envelope having a sealable opening and a resin layer on its inner side and an electrochemical element having terminals, wherein the electrochemical element is inserted in the envelope through the opening and sealed therein. A strip of a material different from the resin layer is disposed in the envelope opening and sealed together by thermal fusion so that the strip serves as a pressure relief valve for relieving pressure within the envelope.
