Stator of brushless motor, brushless motor, and method of manufacturing stator of brushless motor

A stator of a brushless motor, the stator comprising:

• a stator core including a base portion having an annular plate shape and a plurality of teeth protruding from one surface of the base portion in an axial direction and disposed in a circumferential direction;
• and
• a plurality of coils respectively wound by concentrated winding along peripheral surfaces of the plurality of teeth,
• wherein the base portion includes an inner circumferential edge that is recessed radially outward from an inner end of each of the plurality of teeth or the base portion includes an outer circumferential edge that is recessed radially inward from an outer end of each of the plurality of teeth,
• the coils are configured as three-phase coils, and each of the three-phase coils has a plurality of coil portions,
• each of the three-phase coils includes a connecting wire connecting adjacent ones of the coil portions to each other, and
• a part of the connecting wire is disposed in a recessed portion of the inner circumferential edge or the outer circumferential edge of the base portion.
