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.

Lead plate-attached coin-type battery whose lead plate is attached to exclusively either an outer can or a cap

A printed circuit board with a coin type electric element of the present invention has the coin type electric element, and printed circuit board, on which the coin type electric element is fixed by soldering. The coin type electric element have a coin exterior case formed of metal and in a coin shape with an opening; a sealing plate, which is fixed on the opening of the coin exterior case, sealing the coin exterior case; and an insulating seal interposed between the coin exterior case and the sealing plate. The coin exterior case and the sealing plate are composed of a pair of terminals, A lead, whose tip portion is bent toward a surface side of a first terminal face, is connected to a second terminal face of the coin type electric element. A soldering face to be soldered by reflow soldering is provided at the tip portion.
