PROBLEM TO BE SOLVED: To provide an electrochemical cell which is easy to downsize and reduce thickness and has a high energy density and has no connection failure at the connection part of a reed terminal and a current collector, and is highly reliable. SOLUTION: As an external lead terminal for electrically connecting an electrochemical cell element and an external circuit, an exposed part in which a metal reed which is an extension of a part of a metal current collector is drawn out to the outside of the cell from a sealing part of the outer package is used. Furthermore, an aperture is provided on at least one side of the outer package film at the portion where the external reed terminal of the sealing part of the outer package is drawn out, and from this aperture the metal reed being an extension of a part of the metal current collector is exposed, and this exposed part is made the external reed terminal or a connecting part of the external reed terminal.
