Abstract

A one-piece field-pole magnet is manufactured by filling a gap formed between magnetic pieces placed on a plane with an adhesive or resin. During the process, a pushing member applies a pushing force onto each of the magnet pieces in a thickness direction thereof. The pushing member comprises pushing parts each of which pushes each of the magnet pieces, thereby equalizing the pushing forces applied to the respective magnet pieces.
