A motor at least comprising: a stator core including a laminated body where a plurality of stator core sheets is laminated; a stator including a stator coil that uses, as a part of a magnetic core, a tooth included in the stator core; and a rotor rotatably supported via a tip of the tooth of the stator core and an air gap, wherein the stator coil constitutes a spiral coil including annular bodies having a predetermined number of turns, each of the annular bodies includes a conductive wire portion, the conductive wire portion includes a conductor portion and an insulating coating that covers the conductor portion, the conductor portion has a substantially quadrangular cross-sectional shape, a part of each of the annular bodies that is located on each of laminating surface sides of the tooth is defined as a coil wire path portion, a portion that is a part of each of the annular bodies and is located between end portions of a pair of the coil wire path portions in a same direction is defined as a coil end portion, a portion where one end of the coil wire path portion transitions to one end of the coil end portion is defined as a coil corner portion, the stator coil is provided with at least one recessed portion (5e, 5f, 5g, 5h, 5i, 5j, 5k, 51) that is recessed with respect to a virtual envelope surface including an outer peripheral portion of the coil end portion, an outer peripheral portion of the coil wire path portion, and an outer peripheral portion of the coil corner portion in the spiral coil, characterized in that a width of the stator coil at the recessed portion (5e, 5f, 5g, 5h, 5i, 5j, 5k, 51) is narrower than a stator coil width of the annular body of a turn adjacent to the recessed portion (5e, 5f, 5g, 5h, 5i, 5j, 5k, 51) of the spiral coil. the stator coil constitutes a spiral coil including annular bodies having a predetermined number of turns, each of the annular bodies includes a conductive wire portion, the conductive wire portion includes a conductor portion and an insulating coating that covers the conductor portion, the conductor portion has a substantially quadrangular cross-sectional shape, a part of each of the annular bodies that is located on each of laminating surface sides of the tooth is defined as a coil wire path portion, a portion that is a part of each of the annular bodies and is located between end portions of a pair of the coil wire path portions in a same direction is defined as a coil end portion, a portion where one end of the coil wire path portion transitions to one end of the coil end portion is defined as a coil corner portion, the stator coil is provided with at least one recessed portion (5e, 5f, 5g, 5h, 5i, 5j, 5k, 51) that is recessed with respect to a virtual envelope surface including an outer peripheral portion of the coil end portion, an outer peripheral portion of the coil wire path portion, and an outer peripheral portion of the coil corner portion in the spiral coil, characterized in that a width of the stator coil at the recessed portion (5e, 5f, 5g, 5h, 5i, 5j, 5k, 51) is narrower than a stator coil width of the annular body of a turn adjacent to the recessed portion (5e, 5f, 5g, 5h, 5i, 5j, 5k, 51) of the spiral coil.
