A method for manufacturing a contact terminal including a contact portion that slides against a surface of a conductive contact plate. The manufacturing method includes forming a projection in a metal plate by performing a drawing process, wherein the projection projects in a thicknesswise direction of the metal plate and has a larger diameter than the contact portion. The manufacturing method further includes forming the contact portion from the projection by performing a contraction pressing process at least once on the projection so that the diameter of the projection gradually decreases, while the height of the projection remains the same or decreases in a stepwise manner.

A motor-driven compressor includes a compression unit, an electric motor, a housing that includes an accommodating chamber and a wiring connection port, a motor driving circuit that includes a substrate arranged in the accommodating chamber, wiring electrically connected to the substrate and extending out of the housing through the wiring connection port, and a resin sealing member fitted to the wiring connection port. The wiring includes a primary conductor, which has a first end connected to the substrate and a second end, and a secondary conductor, which is connected to the second end of the primary conductor and arranged outside the housing. The secondary conductor includes a wire portion and a sheath that is made of an insulating material and covers the wire portion. The sealing member covers the sheath and a junction between the primary conductor and the secondary conductor.

A rotation plate including a surface, in which a fixed contact terminal slides in contact with the surface of the rotation plate. The rotation plate includes a movable contact plate and a holding member. The movable contact plate forms a predetermined conductive pattern. The holding member holds the movable contact plate and is formed from an insulating resin material. The movable contact plate and the holding member are molded integrally and fixed to each other so that a surface of the movable contact plate is exposed and does not project outward from a surface of the holding member.
