To provide a sheet for a grinding wheel whereby rotational balance of the grinding wheel can be easily adjusted, for instance, even without by a skilled worker.

A sheet main body 22 consisting of paper material is formed in doughnut shape. A scale 23 is printed in a surface 22a of the sheet main body 22. This scale 23 is formed over the total periphery around a center S of the sheet main body 22 serving as an angular center. This sheet 21 for a grinding wheel is fixed thereto with a back surface 22b. This scale 23 serves as an index in the case of relatively moving a balance weight relating to the grinding wheel around an axial line thereof.
