Rotor and method of manufacturing rotor

A rotor comprising:

• a rotor core provided fixedly to a rotation shaft and having a hole extending in an axial direction formed therein;
• and
• a magnet embedded in said hole and extending in said axial direction and extending in a direction inclined relative to a radial direction of said rotor core, wherein
• said magnet partitions said hole in said radial direction to contact a pair of opposite inner surfaces of said hole to define, in said hole, an outer region at an outer side in the radial direction and an inner region being separated from said outer region at an inner side in the radial direction relative to said magnet,
• in said inner region, a resin layer filled with resin and a hollow space unfilled with resin are formed,
• said resin layer covers a radially inner surface of said magnet, secures said magnet to said rotor core from the radially inner side, and is in contact with an inner surface of said hole,
• part of said inner surface is exposed to said hollow space,
• said inner region has a capacity larger than a capacity of said outer region, and
• the outer region is located at a more radially outward position than a radially outer surface of the magnet, and the inner region is located at more radially inward position than a radially inner surface of the magnet;
• the resin layer has a shape of a substantially thin plate and has a first plane which covers the radially inner surface of the magnet and makes a contact with the inner surface of the hole;
• and
• the resin layer has a first surface and a second surface opposing the first surface, the first surface covers the radially inner surface of the magnet and makes contact with the inner surface of the hole, and the second surface faces the hollow space and does not contact the inner surface of the hole.
