Claim 8:
9. An armature comprising:
an armature core provided with a plurality of slots extending in an axial direction;
a plurality of first segment conductors disposed on one side of the armature core in the axial direction and including a first leg portion that extends to the other side of the armature core in the axial direction;
a plurality of second segment conductors disposed on the other side of the armature core in the axial direction and including a second leg portion that extends to the one side of the armature core in the axial direction; and
a coil portion including a joint portion in which at least a part of a first surface that is provided on a tip end portion side of each first leg portion of the plurality of first segment conductors and that is provided so as to extend along the axial direction, and at least a part of a second surface that is provided on a tip end portion side of each second leg portion of the plurality of second segment conductors and that is provided so as to extend along the axial direction are joined in one of the slots or on an outer side of one of the slots in the axial direction, wherein
the first leg portion has a first leg portion body portion that has a thickness in a radial direction that is larger than a thickness in the radial direction of a first surface side part provided with the first surface,
a minimum value of a dimensional variation range of a thickness of the first surface side part in the radial direction among the plurality of first segment conductors disposed in one of the slots is equal to or more than half of a maximum value of a dimensional variation range of a thickness of the first leg portion body portion among the plurality of first segment conductors disposed in one of the slots,
the second leg portion has a second leg portion body portion that has a thickness in the radial direction that is larger than a thickness in the radial direction of a second surface side part provided with the second surface, and
a minimum value of a dimensional variation range of a thickness of the second surface side part in the radial direction among the plurality of second segment conductors disposed in one of the slots is equal to or more than half of a maximum value of a dimensional variation range of a thickness of the second leg portion body portion among the plurality of second segment conductors disposed in one of the slots.
