Abstract: In a motor, a stator includes: a stator core having slots arranged in a circumferential direction; and conductor connection bodies with conductors connected in series and inserted into the slots. A conductor connection body includes: a first portion wave-wound toward one side in the circumferential direction from a first end to a second end; a second portion wave-wound toward the one side in the circumferential direction from a third end to a fourth end; and a folded portion connecting the first and second portions. The first and third ends protrude in an axial direction from different slots in the circumferential direction, and the second and fourth ends protrude in the axial direction from different slots in the circumferential direction. The conductors include a folded conductor that forms a folded portion connecting the second end of the first portion and the fourth end of the second portion.
