A wiring component for a motor coil includes a wire coil configured by a plurality of wire segments arranged in a circumferential direction so as to form a ring shape, each of the wire segments including an arc-shaped main-body portion made of a conductive wire rod bent in an arc shape, protruding portions formed at both end portions of the main-body portion, and upright portions respectively formed at end portions of the protruding portions in a manner of bending one of end portions of each of the protruding portions so that the upright portions protrude in a direction vertical relative to a planar surface including the main-body portion. The wire coil is arranged to form a plurality of layers, thereby forming a cylindrical shape, and the upright portions, at which the adjacent wire segments contact each other in the circumferential direction thereof, are electrically connected to each other.
