An electrodeposited grindstone obtained by embedding abrasive grains in a nickel plated bearing layer due to electrodeposition process and a nickel-phosphorus alloy bearing layer due to chemical plating process formed successively on a grinding part surface of a grindstone base metal. An electrodeposited grindstone obtained by forming a thin plated layer by electrodeposition process on said electrodeposited grindstone which underwent a heat treatment and on the surface of the nickel-phosphorus alloy bearing layer.
