Abstract
A method for producing a resin-bonded magnet, which includes steps of mixing a magnet element and microcapsules each of which contains at least one component of a thermally polymerizable resin composition as a binder component, mechanically breaking at least a part of the microcapsules during formation of a green compact comprising said resin composition and said magnet element to discharge the components of said resin composition from the capsules, and curing said resin to produce the resin-bonded magnet.
