ABSTRACT:
A lead plate-attached coin-type battery is constituted from a combination of a coin-type battery and a positive lead plate. In the coin-type battery, a negative cap seals the aperture of a positive outer can. In a lateral view, the positive lead plate is crank-shaped, and one end thereof is attached to the outer surface of the positive outer can of the coin-type battery. A lead plate is not attached to the negative cap. One or more projections that project in the Z axis direction are provided on the negative cap. In the lead plate-attached coin-type battery, the positive lead plate and negative cap have been attached to respective conductive lands on a circuit board by a solder reflow method.
