The invention discloses a high-toughness cBN (cubic boron nitride)-based ultrahigh pressure sintering material and a cutting tool manufactured by the same and having excellent crack resistance. The high-toughness cBN cubic boron nitride-based ultrahigh pressure sintering material and the cutting tool made of the same material comprise at least one powder particle such as Ti nitride powder particles and Al, alloy of Al and Ti, oxide of Al and nitride of Ti and Al as a combined phase forming ingredient in a cBN-based ultrahigh pressure sintering material including the organization of a hard dispersed phase and a combined phase, besides, as the hard dispersed phase forming ingredient, the high-toughness cBN cubic boron nitride-based ultrahigh pressure sintering material and the cutting tool made of the same material comprise cBN, wherein 50% of the accumulation grain size of the powder particles which form the combined phase is 0.6-0.9 microns, furthermore, when the cBN-based ultrahigh pressure sintering material is diffracted by X ray, a diffraction peak of a composite compound of Ti, Al and N appears within a diffraction angle range that 2theta is not smaller than 40.5 degrees and not larger than 41.4 degrees, and I/I0 is not smaller than 0.15 and not larger than 0.3 when the intensity of the diffraction peak of the composite compound of Ti, Al and N is set to be I and the intensity of the diffraction peak of cBN is set to be I0.
