To provide a forming method for a honing stone for processing non-defectives without causing dispersion.

In the forming method for the honing stone for grinding processed objects, the diameter of abrasive grains of a forming grind stone is selected based on the size of chips discharged when the processed objects are ground by the honing stone, and after the outside dimension of the honing stone is formed, the surface state of the honing stone is formed by using the selected forming grind stone. By the forming of the surface state, on the surface of the honing stone, the abrasive grains are dressed, a chip pocket is formed on one side of the abrasive grains, and a bond tail is formed on the other side.
