Abstract: Provided is a robot arm that is provided with mounting interface portions at both ends of a long resin arm body. Each of the mounting interface portions is provided with: a connecting section that is formed of resin and that is connected to the arm body; and a metal member that is embedded in the resin, which forms the connecting section, and that forms a mounting surface. The metal member is provided with a through-hole that penetrates therethrough in the plate-thickness direction and through which a mounting screw passes, and is embedded in the resin while exposing the mounting surface and a seating surface, for the mounting screw, around the through-hole, the seating surface being located at the opposite side from the mounting surface.
