Place it. As shown in FIG. 10, such a group of electrode plates 6 is sealed inside the bag-like exterior body 8 made of synthetic resin in the form of a film or sheet through the opening 8C at the bottom, and the openings in the second part of the bag-like exterior body 8 are sealed. The tips of the pole columns 1 and 1' are made to protrude outward from sd and sd'. Next, the coating resin 2, 2' of the pole pillar and the opening sd of the bag-like exterior body 8,
sd' and the resin in the opening 8C at the bottom of the bag-like exterior body 8 are thermally welded to each other to seal the exterior body. After sealing,
A predetermined amount of electrolytic solution was injected through the opening 8b of the convex portion 8a which served as a safety valve of the bag-like exterior body to form a battery.

The splash-proof plate is inserted into a bag-like exterior body made of sheet-like or film-like synthetic resin, and the resin is bonded to the resin around the electrode plate group, leaving unwelded parts where the resin is in close contact with each other between the pole columns. In a sealed lead-acid battery, in which the electrolyte is injected into the battery and the unwelded part is used as a safety valve, a mating part is provided in the coating resin of the pole pole, and a mating part opposite to this is provided. A plurality of pole columns and a splash-proof plate are integrated by being fitted and fixed to a synthetic resin splash-proof plate. More preferably, the outer side of the coating resin of the pole column, that is, the welded surface with the bag-like exterior body, is formed into a substantially circular arc shape, and a substantially circular resin reservoir is provided at both ends, and the pole column is tapered in the length direction. In addition, an unwelded portion having a substantially similar shape to the pole pillar insertion portion of the bag-like exterior body is also provided.
