An armature includes an armature core, teeth, a commutator, concentrated winding wires, and distributed winding wires. Each of the teeth includes a first branch portion and a second branch portion. Each of segments in the commutator has a riser. A start end and a terminal end of the concentrated winding wire are pulled out separately in a direction getting closer to the commutator and in a direction away from the commutator. The conductor between the concentrated winding wires is hooked by the riser by which the conductor between the other concentrated winding wires is not hooked. A start end and a terminal end of the distributed winding wire are pulled out separately in a direction getting closer to the commutator and in a direction away from the commutator. The conductor between the distributed winding wires is hooked by the riser by which at least one of the conductor between the concentrated winding wires and the conductor between the other distributed winding wires is not hooked.

In a rotating armature, the numbers of teeth straddled by each of plural coil portions are all the same as each other, three. In plural windings that form the plural coil portions, three individual coil portions that, out of the plural coil portions, are disposed at uniform intervals around the circumferential direction of the armature core and are connected together in series are formed in each of the windings. In each of the windings including the three individual coil portions, one segment out of the plural segments is connected to another segment that has the same phase as the one segment out of the plural segments.

A wire material is hooked to a commutator segment and a commutator segment to form an equalizing line therebetween, and the wire material is wound in a distributed manner between a slot and a slot to form a main winding. Subsequently, the wire material is hooked to a commutator segment and a commutator segment to form an equalizing line therebetween, and the wire material is wound in a distributed manner between a slot and a slot to form a main winding. As described above, a process of forming the equalizing line and a process of forming the main winding are repeated while changing the commutator segment to which hooking is to be performed and the slot in which the main winding is to be formed until the number of times of hooking to one commutator segment becomes the same number for all the commutator segments and the number of times the main winding is formed in one slot becomes the same number for all the slots.
