The present invention provides an adhesive and a method for fixing a permanent magnet to a motor, both of which have high thermal conductivity and high fillability, and can significantly improve the cooling performance of the permanent magnet. An adhesive 6 used for fixing a permanent magnet 5 of a motor 1, wherein the monomer 8 contains a mesogenic group and a polymerizable group in the molecule with respect to 100 parts by weight of the polymer 7 containing the mesogenic group. Was added in an amount of 50 to 500 parts by weight, and 10 to 100 parts by weight of a solvent for dissolving the polymer 7 and the monomer 8 was included. When fixing the permanent magnet 5 to the magnet hole 3 a of the motor 1, first, the adhesive 6 is applied to the surface of the permanent magnet 5, and the solvent contained in the adhesive 6 is volatilized to adhere to the surface of the permanent magnet 5. After the liquid crystal coating layer is formed and the permanent magnet 5 is inserted into the magnet hole 3a of the motor 1, the liquid crystal coating layer is heated to generate an adhesive force, thereby generating a permanent magnet in the magnet hole 3a of the motor 1. 5 is fixed.
