When the final finish-annealing is applied to the coil disposed vertically to the coiling axis, after applying this agent and before the final finish-annealing, a pre-annealing for secondary recrystallization is applied only to the upper part of the coil. The distance from the upper end of the coil at the boundary between the secondary recrystallization range and the non-secondary crystallization range in 10 - 20 number of windings from the outer winding to the inner winding of the coil, is adjusted in the range of 1/24-1/3 of coil center axial length and thereafter, the coil is vertically turned over and the final finish-annealing is performed by directing the secondary recrystallization range side to the bottom side.
