1. A composite material comprising:
a primary phase which is an alloy comprising a metallic element M and a nonmetallic element X and of which includes an amorphous phase in an amount of 50 vol % to 80 vol % based on the entire region of the primary phase; and
a secondary phase which is dispersed in the primary phase and comprises a ceramic compound, the ceramic compound comprising the metallic element M and the nonmetallic element X and represented by MaXb where a and b are each greater than 0,
wherein the metallic element M comprises Fe, Cr, and at least one selected from the group consisting of Mo, Ni, Co, Cu, Ti, V, Nb, Ta, W, Mn and Al; and the nonmetallic element X comprises at least one selected from the group consisting of Si, B, C, N, S and P,
the secondary phase
has a distribution density of 0.2 phase/μm to 1.2 phase/μm; and
a tertiary phase which is dispersed in the primary phase and comprises a crystal phase of the metallic element M.
