Abstract: A motor includes a stator around which an armature coil is wound, a bus bar unit including a coil-connection bus bar electrically connected to the armature coil and an electronic-component-connection bus bar to which a plurality of electronic components is welded, and a bus bar holding member arranged to hold the bus bar unit. The electronic-component-connection bus bar includes an electronic component welding portion including a plurality of welding points at which the electronic components are welded to a leading end of the electronic component welding portion, a base portion held by the bus bar holding member, and a connection portion configured to interconnect the electronic component welding portion and the base portion. A distance between the welding points adjoining each other is larger than a width of a thinnest section of the connection portion.
