PROBLEM TO BE SOLVED: To solve the problem that though there is provided a technology to obtain both a machining rate and satisfactory surface roughness by grinding by use of a grinding stone and loose abrasive, a supplied loose abrasive cannot be satisfactorily held and the loose abrasive to be supplied cannot be used for enhancement of the machining rate and the satisfactory surface roughness because a conventional grinding stone is formed by firmly bonding abrasive grains and bond material.SOLUTION: A grinding stone comprises: fine grinding stone having high hardness and disposed by being stuck into a surface; and resin for maintaining a shape of the fine grinding stone in a state where the fine grinding stones are stuck.SELECTED DRAWING: Figure 3
