PROBLEM TO BE SOLVED: To provide a dressing method in a centerless grinder which enables reduction of dressing time and stabilization of grinding accuracy after dressing and accurate determination of whether a dressing state is good or not. SOLUTION: This dressing method includes a process S2 of rotating a grinding wheel at almost the same speed as that in grinding, a dressing process S4 of rotating a rotary dresser at almost the same peripheral speed as that of the grinding wheel or a slightly faster or slower peripheral speed than it and enabling the rotary dresser to feed the grinding wheel by a specified amount each time when it traverses a whole width of the grinding wheel with the predetermined number of times, and a determination process S6 of determining the dressing state of the grinding wheel by variation of current values and power values of a driving motor of the rotary dresser in the dressing process S4.
