PROBLEM TO BE SOLVED: To provide an annealing method of a tool steel, which can produce a tool steel having a hardness lower than that of conventional ones after annealing and a sufficient hardness after quenching and tempering, a production method of an annealed material for the tool steel, the annealed material for the tool steel, the tool steel using the same and a tool.;SOLUTION: The annealing method of a tool steel comprises preparing the tool steel having a composition adjusted such that a crystallized carbide comprising at least one of Cr, Mo, W and V as a cation is formed and dispersed in an Fe matrix, and annealing it in such a manner that the tool steel is heated and maintained at a temperature ranging from 900C to 1,050C and subsequently slowly cooled at an average cooling rate of 60C/h (preferably 50C/h) in the temperature range of 780-830C.;COPYRIGHT: (C)2005,JPO&NCIPI
