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