PROBLEM TO BE SOLVED: To provide a surface-coated member which has high hardness and tenacity, and is excellent in breakage resistance and wear resistance. SOLUTION: In the surface-coated cutting tool 1 having at least one titanium carbonitride layer 4 on the surface of a base body 2, the titanium carbonitride layer 4 has a fine titanium carbonitride layer 4b formed at least in a part. Specifically, in the fine titanium carbonitride layer, titanium carbonitride particles 8 perpendicularly growing to the surface of the base body 2, exhibit a striature structure when observed in a cross sectional direction, while they grow in random directions to exhibit an acicular structure when the titanium carbonitride layer 4 is observed from above the surface.
