Abstract: Provided is a bipolar lead-acid battery in which the electrolyte is less likely to infiltrate into the interface between a positive electrode lead layer and an adhesive layer, deterioration in battery performance is less likely to occur. A positive electrode (120) of a bipolar electrode (130) of a bipolar lead-acid battery (1) includes a positive electrode lead layer (101) that is formed of lead or lead alloy and is disposed on one surface of a substrate (111), and an adhesive layer (140) that is disposed between the one surface of the substrate (111) and the positive electrode lead layer (101) and bonds the one surface of the substrate (111) and the positive electrode lead layer (101). The substrate (111) is formed of a thermoplastic resin, and the adhesive layer (140) is formed of a cured product of a reaction-curing type adhesive that is cured by reaction between a main agent containing an epoxy resin and a curing agent containing an amine compound. Even in a case where the adhesive layer (140) is immersed in a sulfuric acid with a concentration of 38% by mass at a temperature of 60°C for four weeks, the sulfuric acid does not infiltrate into the interface between the positive electrode lead layer (101) and the adhesive layer (140) .

Abstract: This optical fiber cable is a central-core-type cable in which slotted rods are not used, and is composed of a core, a wrapper, a tension member, a ripcord, a sheath, and the like. The core is formed by twisting together a plurality of optical fiber units without back-twisting. The optical fiber units are formed by twisting together a plurality of intermittently-fixed optical fiber ribbons. A direction in which the optical fiber ribbons are twisted together is same as a direction in which the optical fiber units are twisted together.
