1. An armature comprising:
an armature core provided with a plurality of slots extending in an axial direction; and
a coil part including: first segment conductors of a plurality of phases each including a pair of first leg parts extending toward one axial side in the axial direction, and a first connecting part that connects together end parts on an other axial side of the pair of first leg parts; second segment conductors of a plurality of phases each including a pair of second leg parts extending toward the other axial side in the axial direction, and a second connecting part that connects together end parts on the one axial side of the pair of second leg parts; and a joint part where an end part on the one axial side of one of the first leg parts and an end part on the other axial side of one of the second leg parts are joined together in one of the slots or axially outside one of the slots,
wherein
the first leg parts of each of the plurality of first segment conductors each are disposed so as to be adjacent to the first leg part of a same phase,
the second leg parts of each of the plurality of second segment conductors each are disposed so as to be adjacent to the second leg part of a same phase,
the first connecting part of each of the plurality of first segment conductors is disposed so as to be adjacent to the first connecting part of a different phase,
the second connecting part of each of the plurality of second segment conductors is disposed so as to be adjacent to the second connecting part of a different phase,
the first connecting part and the second connecting part have a higher insulatable voltage value than the first leg parts and the second leg parts,
each of the pair of first leg parts and the pair of second leg parts is not provided with an insulating layer, and
at least a portion of the first connecting part where the first connecting parts of different phases are disposed so as to be adjacent to each other and at least a portion of the second connecting part where the second connecting parts of different phases are disposed so as to be adjacent to each other are provided with an insulating layer.
