Zusammenfassung:A rotor includes a laminated core (51A), a plurality of magnets (52A), and a resin portion (53A). The laminated core (51A) includes a plurality of outer core portions (62A) arranged in a circumferential direction. The plurality of outer core portions (62A) and the plurality of magnets (52A) are alternately arranged in the circumferential direction. In addition, the outer core portion (62A) includes a through-hole (621A) that penetrates in an axial direction. The resin portion (53A) includes a columnar portion (535A) that is disposed inside the through-hole (621 A). Accordingly, the rigidity of the resin portion (53A) is enhanced. In addition, the resin portion (53A) includes a gate mark portion (91A). At least a portion of the gate mark portion (91A) is positioned farther radially inward than the through-hole (621A).
