In the Sb Te basic alloy sintered body sputtering target, when has the organization which the minute carbon or the particle of boron encircles around the Sb Te basic alloy particle, average diameter of the Sb Te basic alloy particle X, designates the particle diameter of the carbon or boron as Y, the Sb Te basic alloy sintered body sputtering target which designates Sb and Te which feature that Y/X is a range 1/10 - 1/10000 as the main component. Improvement of Sb Te basic alloy sputtering target organization is assured, crack initiation of the sinterring target is controlled, occurrence of akingu is prevented at the time of sputtering.
