Abstract:
A surface coated member having improved stability and a longer service life is provided. The surface coated member 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 layer among the layers is a layer including hard particles. The hard particles include a multilayer structure having a first unit layer and a second unit layer being layered alternately. The first unit layer includes a first compound. The second unit layer includes a second compound. The first compound and the second compound are respectively made of one or more kind of element selected from the group consisting of a group 4 element, a group 5 element, a group 6 element of a periodic table, and Al, and one or more kind of element selected from the group consisting of B, C, N, and O.
