Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat radiation blade for cutting capable of radiating friction heat generated during cutting to suppress the progress of wear due to the reduction of hardness of a cutting edge tip part and maintaining cutting performance for many hours. SOLUTION: A plurality of through holes 4 or non-through holes are provided on a side face of the blade for cutting, and copper, aluminium, gold, silver, zinc and alloy 5 of them which have excellent heat conductivity are filled into the through holes 4 or the non-through holes to radiate friction heat generated during cutting and suppress rise of temperature of the cutting edge tip part 1 in order to prevent softening and maintain resistance to wear so that initial shape is held for many hours and the reduction of cutting performance is suppressed.
