When a work W is cut by moving a wire in an axial direction thereof while the wire is pressed onto the work and an abrasive liquid which is made by dispersing abrasive grains in a dispersion medium is interposed between the work and the wire, a flow of the wire is formed, and the wire is pressed onto the work while moving under the liquid level of the abrasive liquid whose flow is formed. The work is cut in the abrasive liquid so that a sufficient amount of the abrasive grains can be supplied between the work and the wire for a long time.
