PROBLEM TO BE SOLVED: To provide a coin-type electrochemical cell that stably supports a cell during mounting by solder reflow. SOLUTION: An upper terminal of an electrochemical cell includes a first part, which is bonded to an electrode on the upper-face side and expands toward the edge part of the upper face of a cell body, a plurality of second parts downwardly extending from the first part, and a plurality of third parts that are bent from each of the lower ends of a plurality of the second parts and extend toward a radial direction of the cell body. Projections of the upper and lower terminals onto a plane including the lower face of the cell body are almost stored in a square circumscribing a projection of the cell body onto the plane. Projections of a plurality of the second parts onto the plane are arranged near two or more corners of the square. COPYRIGHT: (C)2009,JPO&INPIT
