摘要： An optical processing structure of an optical fiber includes: an optical fiber that includes a core, a cladding, and a coating, the coating being partially removed; a thermally conductive protective material made of a silicone-based thermally conductive compound and provided around the cladding in a coating removed region of the optical fiber; and a thermally conductive base material on which the optical fiber is placed. The thermally conductive protective material contains a filler having a refractive index higher than that of the cladding. The filler is present in a region where evanescent light seeping out of the cladding is present when cladding mode light propagating in the cladding is totally reflected.

摘要： 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) .
