Abstract:
A surface coated member having improved stability and a longer service life is provided. The surface coated member of the present invention includes a base member and a hard coating formed on a surface thereof. The hard coating is constituted of one or more layers. At least one of the layers is formed by a CVD method and includes a multilayer structure having a first unit layer and a second unit layer being layered alternately. The first unit layer includes a first compound containing Ti and one or more kind of element selected from the group consisting of B, C, N, and O. The second unit layer includes a second compound containing Al and one or more kind of element selected from the group consisting of B, C, N, and O.
