Abstract

A coil bobbin for a stator of an electric motor includes a body part in a rectangular column shape around which a conductive wire is to be wound, and a first flange part provided at an end of the body part. The body part is structured so that the conductive wire starts to be wound around the body part from a root part which is an end part on the first flange part side and, in a case that a corner of the root part which is a starting point where the conductive wire starts to be wound is referred to as a first corner part, a face of the first flange part directed to the body part side is formed with a groove part which passes at a position adjacent to a position of the first corner part and guides the conductive wire to the first corner part.
