A stator (10) includes a stator core (14) that has slots (12) that are provided at plural parts in a circumferential direction, and plural coil units (U1) and the like that are wound on the stator core (14). The plural coil units (U1) and the like include a first coil unit (U5) that has a first insulating layer (50) with a first dielectric constant, and a second coil unit (U1) that has a second insulating layer (54) with a second dielectric constant lower than the first dielectric constant. The slots (12) include a reference slot (S8) in which the first coil unit (U5) is inserted and an input terminal side slot (S7) in which the second coil unit (U1) that is connected on an input terminal side with respect to the first coil unit (U5) in terms of the connection order is inserted, and the coil units (U1, U16) that are placed in the input terminal side slot (S7) include the second coil unit (U1) having the second insulating layer (54).
