PROBLEM TO BE SOLVED: To provide a coin type electrochemical cell in which identification of product display is easy regardless of existence or non-existence of a terminal. SOLUTION: Product displays are displayed at two or more places on the bottom face or side face of an electrode case, and with respect to the product displays at least at two places, the distance from the center of the product display to the center of the bottom face of the electrode case is made 0.32×D or more against the diameter D of the electrochemical cell, and they are arranged mutually at a position of 120-240 degrees and the dimensions of the terminals are made, width : 0.5×D or less, length of the portion covering the bottom face part of the electrode case: 0.75×D or less, and the corner shape of the terminal end part: R or C: 0.25×D or less.
