PROBLEM TO BE SOLVED: To provide a grinding wheel capable of preventing generation of sagging of an outer peripheral part with a simple structure and a grinding device using the grinding wheel. SOLUTION: This circular annular shaped grinding wheel 1 has a grinding surface 2 for grinding an object to be ground on one side. Grinding area abutting on the object to be ground in an inner peripheral part 4 of the grinding surface 2 is narrower than grinding area in the outer peripheral part 5 of the grinding surface 2. As a result, workload per unit area in the inner peripheral part 4 is increased, and thereby when the grinding wheel 1 is applied to a double head plane grinding device, wear of the outer peripheral part 5 and the inner peripheral part 4 can be made uniform.
