PROBLEM TO BE SOLVED : To provide a bonded structure using a magnet adapted to enable the effective elimination of the defective solidification of an adhesive material that is chemically inactive with respect to a nickel plated coating, reduce variations in adhesion strength but obtain large adhesive strength and also obtain high efficiency in adhesion-bonding work.SOLUTION : The magnet 2 has an R-TM-B-based rare earth magnet body 4 that contains R, TM and B wherein the R denotes at least one of rare earth elements including Y and TM denotes transition elements, containing Fe as a base component; a protective film 6 made of a nickel coat film formed on the surface of the magnet body; and a phosphate coated film 8 thinner than 0.1 μm in thickness formed on the surface of the protective film subjected to phosphate treatment using a processing liquid that does not contain fluoride. The adhesively bonded structure is constructed by bonding an iron member to the side of the phosphate coated film 8 of the magnet 2 with an adhesive. |
