PROBLEM TO BE SOLVED: To provide an electrochemical cell with a terminal which has heat resistance and durability and can be firmly jointed with a circuit board of a small-sized electronic device on which the cell is mounted, and moreover has high reliability and can be surface-mounted by a reflow automatic mounting.SOLUTION: The electrochemical cell with a terminal which can perform a reflow automatic mounting includes a metal-made sealed outer envelope 2 in which a power generation element 7 and an electrolyte E are housed, a pair of terminals 3 connected to positive and negative electrodes of the power generation element 7 and extracted outside of the outer envelope 2, an external terminal 5 which can be connected to a circuit board on which the cell is mounted, and at least one fixed terminal 11 connectable to the circuit board. The external terminal 5 and the fixed terminal 11 are laser-spot-welded to the terminal 3 or the outer envelope and are provided with a plurality of welding points 25 on each of the welded sites. |
