Abstract
An electrochemical device includes a storage element in which two types of electrodes are superposed on each other with a separator interposed therebetween and an outer container made of a flexible film that houses the storage element and an electrolyte solution, the two types of electrodes each including an active material-applied portion where an active material layer is formed on current collector, and an active material-non-applied portion, wherein each of the two types of electrodes is provided with an electrode terminaland support tab, one end portion of electrode terminalbeing superposed on the active material-non-applied portion of the electrode in the outer container, the other end portion of electrode terminalextending to an outside of the outer container, support tabsandwiching the active material-non-applied portion along with the one end portion of electrode terminalin the outer container, and the active material-non-applied portion, electrode terminal, and support tabare joined at a position where they are superposed on one another. Support tabhas a planar shape without any corner portion of 90 degrees or less.
