A method of truing a grinding wheel capable of accurately truing the wheel surface of the grinding wheel in a short time in a grinding device having the conductive grinding wheel, comprising the steps of, when the flat annular grinding wheel surfaces 10a, 10a of a pair of grinding wheels 1, 2 disposed opposedly to each other are trued simultaneously, for example, disposing a discharge truing electrode 20 between the grinding wheel surfaces 10a, 10a of both grinding wheels 1, 2 and traversing the electrode parallel with and relative to both grinding wheel surfaces 10a, 10a while applying a discharge truing to the grinding wheel surfaces in the state of no-contact with both grinding wheel surfaces 10a, 10a by a discharge action between the discharge truing electrode 20 and both grinding wheel surfaces 10a, 10a.
