Abstract

An object of the present invention is to provide a crystalline radically polymerizable composition for fixing a magnet of a rotating electric machine rotor core, which is excellent in handleability around room temperature, excellent in fluidity from the injection step to the curing step, and excellent in strength of the cured product. A crystalline radical polymerizable composition for fixing a magnet of a rotating electric machine rotor core of the present invention is characterized by fixing the magnet inserted in a magnet accommodating portion provided in a rotor core of a rotating electric machine formed of a laminated steel sheet and the laminated steel sheet,
