Reference numeral 3 denotes a dish-shaped sealing lid made of stainless steel or the like, and a lithium metal 4 serving as a negative electrode is pressed into the inner surface of the lid. 5 is a separator impregnated with 7L of non-aqueous solution. Reference numeral 6 denotes a gasket made of polypropylene or the like, which hermetically seals the space between the case 1 and the sealing plate 3 by bending the two ends 1a of the rising portion of the case 1 inward. A heat-shrinkable insulating halon tube 7 made of polyvinyl chloride or the like insulates the positive electrode case 1 and the negative electrode sealing plate 3 from short-circuiting. Reference numeral 8 denotes a strip-shaped lead terminal which is a feature of the present invention, and is intended to be connected to a printed circuit board, and is spot-welded to the positive electrode case 1 and the "1" plate 3, respectively. As shown in FIG. 2, this lead terminal 8 was made of a rolled metal strip and was punched out at right angles to the rolling direction. Therefore, as shown in FIG. 3, the tip 8a of the strip lead terminal 8 has a
It had the disadvantage that its mechanical strength against bending was weak because of the stripes that appeared during rolling.

が入っているものに比べ折り曲げ強度が増加する。SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is characterized in that a strip-shaped lead terminal is manufactured by punching out a strip-shaped metal material in a direction parallel or diagonal to the rolling direction. In this way, the stripes that are parallel to the rolling direction become parallel or oblique to the longitudinal direction of the strip-shaped lead terminal, so that the stripes appear at right angles to the tip of the strip-shaped lead terminal. The bending strength is increased compared to the same.

In FIG. 4, reference numeral 9 indicates a rolled strip having stripes parallel to the rolling direction A thereof. Since the lead connection terminal 8' is punched out parallel to the rolling direction of the metal 9, the tip 8a of the lead terminal 8' has stripes parallel to its narrow width direction, as shown in FIG. , making it more resistant to bending. This lead terminal 8' is shown in FIG. In FIG. 5, the stripes of the metal moon are shown for explanation purposes. This lead terminal 8' is still welded and fixed to the positive and negative terminals of the battery as in the conventional case. Although the above example shows that the lead terminal is punched out in parallel to the rolling direction of the strip metal, it is also possible to punch out the lead terminal in an oblique direction as shown in Fig. 6 to reduce the bending strength. can be kept high.
