Zusammenfassung:	An electric motor (30) for an air conditioner includes: a rotor (40) configured to rotate freely about a rotary shaft; and a stator core (32, 32a, 32b, 32c, 32d, 32e, 32f, 32g, 32h, 32i) arranged outside the rotor (40). The stator core (32, 32a, 32b, 32c, 32d, 32e, 32f, 32g, 32h, 32i) includes: an inner yoke portion (41) in an annular shape; a tooth portion (35) extending inward from the inner yoke portion (41) in a radial direction; an outer yoke portion (43) in an annular shape arranged outward of the inner yoke portion (41) in the radial direction; a plurality of beam portions (42) extending in a circumferential direction between the inner yoke portion (41) and the outer yoke portion (43); an inner joint portion (44) configured to join the inner yoke portion (41) and each of the beam portions (42) in the radial direction; and an outer joint portion (45) configured to join the outer yoke portion (43) and each of the beam portions (42) in the radial direction.
