The abrasive stone chips are each formed into a block shape having a surface in which two or more kinds of plate-shaped abrasive stone members containing abrasive grains and a binder are exposed to the outside by overlapping the two or more kinds of abrasive stone members. The surfaces exposed to the outside in the abrasive stone chips serve as grinding processing surfaces that get contact with the work piece.
