PROBLEM TO BE SOLVED: To provide a simple method for manufacturing an integrated magnet body, having high dimensional accuracy and exhibiting superior corrosion resistance and adhesive strength. SOLUTION: The method for manufacturing the integral magnet body comprises step (1) for electrodepositing on the surface of respective magnet pieces a cationic electrodeposition coating material, which contains a thermosetting resin composition comprising an epoxy resin, having a sulfonium group and a propargyl group and has a minimum value of complex viscosityηin the thermosetting process of not smaller than 10 (Pa s); step (2) for provisionally drying individual magnet pieces electrodeposited in the process (1); step (3) for laminating the individual magnet pieces provisionally dried in step (2); and a step (4) for bonding and integrating the magnet pieces together, by heating the laminate, comprising a plurality of the magnet pieces laminated in step (3), to finish the thermosetting process of the thermosetting resin.
