A motor for a compressor includes a rotor and a stator disposed radial outside of the rotor. The stator includes a stator core having oppositely facing axial end faces, insulators disposed so as to face the end faces, and coils wound on the stator core and the insulators. Each of the insulators has an annular part, a plurality of teeth protruding radially inwardly from an inner circumferential surface of the annular part at specified circumferential intervals, an outer circumferential wall having one end fixed to an end face of the annular part, and protrusions disposed on an outer circumferential surface of an outer circumferential wall of an insulator. At least one lead wire of the coils is drawn out to an outer circumferential side of the outer circumferential wall, guided along the outer circumferential wall, and passed on a side of the protrusions facing the stator core.
