PROBLEM TO BE SOLVED: To provide a hard film coated sintered member capable of realizing a tough hard film coated on a base material formed of a sintered body to prolong the lifetime. SOLUTION: Any one of a ceramic film, a BCN-based super-hard material film, and a mixed film of metal and ceramic is coated on a surface of a base material formed of the sintered body, and has a dislocation structure having the dislocation density of the uniformly distributed, straight dislocation being 1×10<SP>4</SP>to 9×10<SP>10</SP>cm<SP>-2</SP>in a range of tens ofμm or under from the interface of the base material formed of the sintered body.
