SURFACE-COATED BORON NITRIDE SINTERED BODY TOOL
A surface-coated boron nitride sintered body tool is provided, in which at least a cutting edge portion includes a cubic boron nitride sintered body and a coating film formed on a surface of the cubic boron nitride sintered body. The coating film contains Si and includes a B layer formed by alternately stacking one or more of each of a B1 compound layer and a B2 compound layer that are different in composition. A ratio between an average thickness t 1 of the B 1 compound layers and an average thickness t2 of the B2 compound layers is defined as t2/t1 that satisfies a relation of 0.5 < t2/t1 ¤ 10
