Disclosed is a method of effectively dressing a grinding wheel of high grain concentration having a high wheel number usable for an ultrahigh precision processing. When a grinding wheel (,) is trued (i.e., formed into a predetermined shape) by using a truing tool (,), the grinding wheel (,) is dressed by feeding a coolant W in which abrasive grains (,) for dressing are dispersed into a space between the truing tool (,) and a surface (,) of the grinding wheel (,). Therefore, it is possible to easily true and dress the ultra-fine grinding wheel usable for ultra-high precision processing, without being affected by the manufacturing limit of the dressing tool, being different from the dressing method using a dressing tool.
