The invention provides a cermet composite material that can improve a bond strength between a cermet part and a non-cermet part without heat treatment at high temperature. The cermet composite material according to the invention comprises a cermet part including hard carbides dispersed in a metallic phase and a non-cermet part consisting of a Ni-based alloy including 50% by mass or more of Ni with the cermet part being formed on the non-cermet part by additive manufacturing, wherein the cermet composite material comprises an intermediate layer including both components of the cermet part and components of the non-cermet part between the cermet part and the non-cermet part, and the non-cermet part consists of the Ni-based alloy including 3.0% by mass to 15.0% by mass of Ti or the Ni-based alloy including 0.5% by mass to less than 3.0% by mass of Ti and 4% by mass to 15% by mass of Nb and Ta in total.
