Zusammenfassung:A rotor includes: a rotor core (131) formed by stacking a first sheet member (131A) and a second sheet member (131B) and having a first magnet-inserted hole (1311) and a second magnet-inserted hole (1312) located radially outward relative to the first magnet-inserted hole (1311); magnets (132) inserted respectively into the first and second magnet-inserted holes (1311, 1312); and a resin portion (133) injected into the first and second magnet-inserted holes (1311, 1312). The first sheet member (131A) has a first hole (1311A) and a second hole (1312A) constituting the first and second magnet-inserted holes (1311, 1312) respectively. The second sheet member (131B) is located at at least one axial end of the rotor core and has a portion covering a part of the first hole (1311A).
