ている。2. Description of the Related Art In recent years, portable electronic devices using batteries have rapidly become smaller and thinner. Along with this, the batteries used also need to be smaller and thinner. In particular, batteries attached to card-shaped devices are desired to be as thin as possible, and their electrical connection methods are also required to be simple and highly reliable. In response to these demands, various thin batteries have been developed in recent years.

の欠点があった。[Problems to be Solved by the Invention] Conventionally, this type of thin battery has no terminal section, so electricity must be extracted from the top and bottom of the battery using means such as battery press springs, which increases the thickness of the device. It had the disadvantage of being thicker. Also, a method has been proposed in which lead plates are spot welded to batteries and connected to equipment, but when spot welding or laser welding lead plates to lithium batteries, the melting point of lithium is 1.
Since the temperature is 79℃, lithium melts and penetrates the separator.
This has disadvantages such as causing internal short circuits and increasing manufacturing costs.

FIG. 1 is a cross-sectional view showing one embodiment of the flat plate battery of the present invention applied to electrical equipment. In FIG. 1, a battery A has a positive electrode current collector plate 1 and a negative electrode current collector plate 2 made of materials such as stainless steel and nickel, which also serve as the exterior, and a positive electrode mixture 3 containing manganese dioxide as a main component as a power generating element, and a separator 4.
is placed. 5 is lithium, which is a negative electrode active material, and is pressure-bonded to the inside of the negative electrode current collector plate 2. The power generating element consisting of the above-mentioned 3, 4, and 5 is sealed by heat sealing with the current collector plates 1 and 2 and the sealing resin 6. In addition, the sealing resin 6
also serves as an electrical insulating layer. Further, 7 and 8 are permanent magnets with different polarities, and in this example, magnet 7
is buried in the positive electrode terminal portion 9, and the portion facing the electrical equipment serves as the south pole. Further, the magnet 8 is embedded in the sealing resin 6 of the negative electrode terminal portion 10 so that the portion facing the electrical equipment becomes the north pole. Furthermore, positive and negative terminal parts 9, 1
0 are arranged on the same plane.

。Reference numeral B indicates a battery mounting surface on the electrical equipment side, and 11 is a magnetic positive terminal portion for introducing power into the equipment, and the N pole is disposed on the outer surface. Moreover, 12 is a negative electrode terminal portion which also has magnetic properties, and the S pole is arranged on the outer surface. As a result, the positive and negative terminals on the battery side and the positive and negative terminals on the electrical equipment are attracted to each other by magnetic force, so that the positive and negative terminals cannot be connected in reverse. Note that FIG. 2 is a bottom view of the battery of the present invention shown in FIG. 1.

This makes it possible to easily and reliably contact the positive and negative electrodes, thereby preventing incorrect connection of the positive and negative electrodes. Furthermore, the battery can be easily attached and detached without sacrificing the advantage of having a thin battery, and can be applied to lithium secondary batteries, capacitors, and the like. The present invention can be applied to electronic devices such as IC cards, electronic notebooks, watches, and office automation equipment, and has great industrial value.
