PROBLEM TO BE SOLVED: To improve acid resistance and corrosion resistance. SOLUTION: In this conditioner 20, plural abrasive grains 23 are fixed by a metallic bond phase 22 by plating. The metallic bond phase 22 is formed by forming an abrasive grain retention layer 25 of Ni or an Ni-based alloy on a base layer 24 for positioning and fixing the abrasive grains 23, and forming a ternary alloy layer 26 composed of the balance Ni-5 to 15 wt.% W-5 to 15 wt.% P as an outermost layer. The ternary alloy layer 26 is formed by electroless plating. Preferably, the conditioner 20 is heat treated at 300-600 deg.C. |
