Stator with core having busbars having integrally molded insulating resin

A stator comprising:

• a core including a yoke having a tubular shape and a plurality of teeth that protrude from an inner peripheral surface of the yoke to inside of the yoke;
• a plurality of molded coils arranged on the plurality of teeth;
• a bus bar electrically connected to the plurality of molded coils and electrically connected to an external circuit;
• and
• an insulating resin having insulation properties, wherein
• the insulating resin includes:
• a first resin portion that molds the bus bar;
• a second resin portion that is arranged between the plurality of teeth and the plurality of molded coils;
• and
• a third resin portion that molds the plurality of molded coils,
• the first resin portion, the second resin portion, and the third resin portion are made of same resin material,
• the insulating resin does not include boundary surfaces that divide the first resin portion, the second resin portion, and the third resin portion, and
• the first resin portion, the second resin portion, and the third resin portion are integrally molded.
