PROBLEM TO BE SOLVED: To provide a high-reliability flat plate type electrochemical cell which is easily made high in energy density, small-sized and thin and free of a defect in connection with a collector due to deformation and breakage of a lead terminal. SOLUTION: Employed is a structure provided with a protection frame protecting an external lead terminal led out of a sealing body of an exterior body. Namely, an electrochemical cell having an electrochemical cell element which is carried on a metal pyroelectric body and has at least a couple of electrodes functioning as positive or negative electrodes and an ion conductive electrolyte, the bag-shaped exterior body which is formed of a resin film or a laminate film of resin and metal foil and in which the electrochemical cell is stored inside and hermetically sealed, and a couple of metal leads for electrically connecting the couple of electrodes of the electrochemical cell element to an external circuit is in such a structure that tip parts of the metal leads are held or protected by a protection frame part constituted by leading at least of one of the gold leads out of the cell from the sealing part of the exterior body and extending the exterior body from a peripehral edge of the sealing part.
