Cylindrical bonded magnet, method of producing cylindrical bonded magnet, and mold for forming cylindrical bonded magnet

A mold for forming a cylindrical bonded magnet, comprising:

• an inner mold portion including a non-magnetic component, an outer mold portion including a non-magnetic component, a first orientation magnet, and a second orientation magnet,
• wherein the inner mold portion has an outer surface that forms a circle when viewed in a cross-section taken in a direction,
• the outer mold portion has an inner surface that is spaced from the outer surface of the inner mold portion and forms a circle when viewed in said cross-section taken in said direction,
• the first orientation magnet and the second orientation magnet are located to sandwich the inner mold portion and the outer mold portion so that a magnetic field is applied in said direction during magnetic field orientation,
• when viewed in said cross-section taken in said direction, a first distance is shorter than a second distance,
• wherein the first distance is a straight line distance along a magnetic field application direction between the first orientation magnet and the second orientation magnet and is tangent to the circle defined by the inner surface of the outer mold portion, and
• wherein the second distance is a straight line distance along the magnetic field application direction between the first orientation magnet and the second orientation magnet and passes through a center of the circle defined by the outer surface of the inner mold portion.
