ードの電源電池として使用できる。As the above-mentioned measures, the applicant has taken the measures shown in Figures 2 (A) and (B).
As shown in the figure, a positive electrode mixture 4 and a negative electrode sheet 5 are placed between metal sealing plates 1.2 which also serve as positive and negative electrode terminals with a separator 3 interposed therebetween.
The periphery between each of the metal sealing plates 1.2 is sealed with a frame-shaped insulating sealing body 6, and a part of each of the metal sealing plates 1.2 is further covered with the insulating sealing body 6. A flat battery (
Patent Application No. 59-247768) was proposed. In a flat battery having such a structure, the metal sealing plate 1.2 is provided with extending lead portions 7.8, so when loading it into an IC card, each of the lead portions 7.8 is provided with the insulating sealant. To make it possible to connect strip-shaped lead terminals by spot welding without causing heat damage. As a result, the flat battery can be used as a highly reliable power supply battery for an IC card without compromising its thinness.

とが困難となる。However, since a battery having such a structure is itself thin, the metal sealing plate used therein is extremely thin, and the lead portion of the metal sealing plate is easily bent. If the lead portion 7 of one metal sealing plate (for example 1) is bent, it may come into contact with the other metal sealing plate 2 and cause an external short circuit, posing a problem in terms of reliability. . Note that it is conceivable to shorten the length of the lead portion of the metal sealing plate to prevent the lead portion from coming into contact with the mating sealing plate when the lead portion is bent. However, when the length of the lead portion of the sealing plate is shortened, it becomes difficult to carry out a sporatowelg for connecting a band-shaped lead terminal to the lead portion.

To provide a flat battery which can be connected and which can be prevented from directly contacting the other metal sealing plate and causing an external short circuit even if an extended lead part of one metal sealing plate is bent.

形電池である。In the present invention, a power generation element in which a positive electrode mixture and a negative electrode sheet are laminated via a separator is arranged between two metal sealing plates that also serve as positive and negative electrode terminals having different external dimensions, and In a flat battery having a structure in which the periphery is sealed with a frame-shaped insulating sealing body, a lead portion is formed by extending a portion of one opposing side of each of the metal sealing plates in the same direction and shifted from each other, and further The width of the frame-like part on one side of the insulating sealing body corresponding to the lead part is widened, and the outer edge of each metal sealing plate from which the lead part extends is positioned so as to be set back from the outer edge of the wide frame-like part. This is a flat battery that is characterized by being designed to

き、薄形のＩＣカード等の特長を活かすことができる。According to the present invention described above, a lead portion is formed by extending a portion of one opposing side of the metal sealing plate in the same direction and shifted from each other, and further, a portion of one side of the insulating sealing member corresponding to the lead portion is extended in the same direction and shifted from each other. By widening the width of the frame-like part and positioning the outer edge of each metal sealing plate from which the lead part extends out from the outer edge of the wide frame-like part, an IC card or the like can be loaded. In this case, a pair of belt-shaped lead terminals can be connected to each of the lead parts using a sporatowelg, so the thickness between the lead terminals can be approximately the same as that of a flat battery, making use of the features of thin IC cards, etc. be able to.

行なうことができる。In this case, since the heat of the sporatowelg is not directly applied to the insulating sealing body of the battery, thermal damage to the insulating sealing body can be prevented. Furthermore, since the lead portions of each metal sealing plate are arranged on the same side of the insulating sealing body, when the metal sealing plate is loaded into an IC card or the like, connection with the strip-shaped lead terminal or the like becomes easy. In addition, if the lead part of one metal sealing plate is bent, the lead part is inserted into the frame-shaped part of one side of the insulating sealing body where the lead part is located, and the outer edge of the other metal sealing plate is bent into the wide frame-shaped part. Since the lead portions are sufficiently set back from the outer edge of the metal sealing plate and the lead portions are arranged offset from each other, it is possible to prevent the lead portion from coming into contact with the other metal sealing plate or its lead portion and causing an external short circuit. Furthermore, by making the outer dimensions of one metal sealing plate smaller than the other metal sealing plate and bonding the outer edge of the metal sealing plate onto the insulating sealing body so as to be slightly set back from the outer edge of the sealing body, When a conductor comes into contact with the periphery of the battery, it is possible to prevent the metal sealing plates of the battery from being short-circuited to the outside through the conductor. Incidentally, since the length of the lead portion of each metal sealing plate itself can be made sufficiently long, spot welding for connecting a lead terminal to the lead portion can be easily performed.

位置させるようにしたことを特徴とする扁平形電池。A power generation element in which a positive electrode mixture and a negative electrode sheet are laminated via a separator is placed between two metal sealing plates that also serve as positive and negative terminals with different external dimensions, and a frame-shaped insulator is placed around each metal sealing plate. In a flat battery having a structure sealed with a sealing body, a lead portion is formed by extending a portion of one opposing side of each of the metal sealing plates in the same direction and offset from each other, and further forming a lead portion corresponding to the lead portion. The width of the frame-like part on one side of the insulating sealing body is widened, and the outer edge of each metal sealing plate from which the lead part extends is positioned retreating from the outer edge of the wide frame-like part. A flat battery.
