Abstract: A thermistor includes a case having a bottom section at one end and an opening section at the other end, a thermistor element housed in the case, a conducting wire housed in the case and connected to the thermistor element, and a lead wire connected to the conducting wire.The lead wire has a first portion including an insulating coating, and a second portion connected to the conducting wire and exposed from the insulating coating. A resin is filled up to a position away from an end edge of the opening section toward the bottom section so as to enclose at least the thermistor element, the conducting wire, and the second portion. The first portion is guided out of the resin to the outside of the case. An inner peripheral surface of the opening section is curved so as to increase an opening area of the opening section.

Abstract: A stator includes a stator core, a plurality of phase windings, a neutral line and a fixing portion. The plurality of phase windings is wounded a plurality of times by a predetermined winding method crossing between a plurality of slots. One lead end of each phase winding is a neutral point connecting portion, and the one lead end is pulled out from an axially end portion of the stator core. The neutral line connects the neutral point connecting portions of the phase windings of different phases together. The neutral line is separate from the phase windings. The fixing portion fixes a first phase winding that is connected to the neutral line. A second phase winding is adjacent to the first phase winding together.
