After the protective adhesive layer is cured, the metal core material is cured. A method for manufacturing a handle member in which a coating layer containing a photocatalyst is formed on the outer surface of a protective adhesive layer and hardened by dipping the material into a coating agent containing a photocatalyst in which the material is melted and pulling it up.
  8. On the outer surface of the metal core material serving as the base material, a coating agent containing the molten photocatalyst is applied by either brush coating or spray coating to form a coating layer containing the photocatalyst, and the coating layer is cured. A method for manufacturing a handle member.
  9. On the outer surface of the metal core material serving as the base material, a molten protective adhesive is applied by brush or roller coating or spray coating to form a protective adhesive layer, and after the protective adhesive layer is cured, A method for manufacturing a handle member, in which a coating agent containing a photocatalyst is applied to the outer surface of a protective adhesive layer by brush coating or spray coating to form a coating layer containing a photocatalyst, and the coating layer is cured.
