PROBLEM TO BE SOLVED: To lower cutting resistance and to reduce dispersion and chipping of thickness of a work by covering all or a part of an exposed surface of a disc base plate made of high speed steel with a chrome plated film. SOLUTION: A high speed steel made base plate 1 is set in a mold. A diamond layer 2 is fastened on an outer peripheral surface of the high speed steel made base plate by blending diamond abrasive grains in a resin bond with polyimide resin as a main component and silicon carbide powder as a filler, filling a uniformly mixed mixture in the mold, heating and pressurizing it. This diamond layer 2 is applied with truing dressing by a dressing machine. Thereafter, this diamond layer 2 of a diamond cutting wheel and a base plate hole part are marked with insulating varnish, only both surfaces of the base plate are covered with chrome plating, a chromium plated film 4 is formed, and a resin bond diamond cutting wheel is made.
