を構成している。 As shown in FIGS. 1 and 3, these elements are housed side by side in each chamber 10 of the battery case with the cathode and anode active material layers 1a and 2a facing each other with a separator 11 in between. The active material layers 1a and 2a are brought into close contact with the flat current collector 4 adhered to the outer casing 5, and the frame 8 and the outer casing 5 are bonded together by adhesive or high-frequency welding while applying an appropriate construction pressure. Seal tightly. Next, the terminal portions 7 of each unit cell A are connected through the through holes 6 with the conductive members 12. Conductive member 12
For example, copper foil is used. Then, in order to prevent mechanical damage to the conductive member 12 and to provide electrical insulation, the conductive member 12 is covered with a polyester film or the like. Thereafter, a sulfuric acid electrolyte having a specific gravity of 1.30 is injected into the separator 11 through an inlet (not shown), impregnated and held in the separator 11, and the inlet is sealed to obtain a thin lead-acid battery. In the figure, reference numeral 15 is a rivet terminal, which is connected to the conductive member 12 and constitutes an external terminal.

あつた。 A problem with the above lead-acid battery is that the conductive member 12 protrudes to the outside of the exterior body 5. Since the conductive member 12 is usually formed of a thin member such as copper foil or a thin wire, its mechanical strength is extremely low. Therefore, a protective coating such as a polyester film is used, but this is not very strong. Furthermore, there was a risk that the electrolytic solution would adhere to the conductive member 12 and corrode the conductive member 12.

めである。 In FIG. 5, the conductive member 12 is covered with a coating 13 made of epoxy resin. The coating 13 may be formed by applying an epoxy resin liquid to the conductive member 12, or may be a sheet-like film that wraps around the conductive member 12. The portion indicated by the two-dot chain line is a portion that will become the gate 14 when the exterior body 5 is resin molded by injection molding. The reason why this gate 14 is provided at the approximate center of the coating 13 as shown in the figure is to have the effect of causing the epoxy resin to harden quickly due to the high temperature and high pressure resin flowing through the gate 14.
