Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coin-shaped storage cell with improved liquid-leakage resistance during reflow soldering for processing at a higher temperature than usual. SOLUTION: The coin-shaped storage cell is composed of an element in which a pair of electrodes 16 is arranged oppositely to each other via an insulating separator 18, and an upper lid 13 (a cathode side) for hermetically sealing the element via insulating annular packing 15 after storing the element in a metal case 11 (an anode side). The coin-shaped storage cell is composed of a structure in which a face contacting the electrodes 16 of the metal case 11 is internally extruded, a step-like external terminal 20 is connected to the outer face of the internally extruded metal case 11, and a step-like external terminal 21 is connected to the outer face of the upper lid 13 so that its tip is flush with the tip of the external terminal 20 on the metal case 11 side.
