Abstract
A sintered titanium boride ceramic body consists essentially of a matrix having a three-dimensional net-work structure and consisting essentially of TiC and at least one MB selected from transition metals in a mixing crystals and solid solutions condition, TiB.sub.2 particles separately placed in the matrix, and a grain boundary formed in the periphery of each of the TiB.sub.2 particles. The grain boundary is in a mixing crystals and solid solutions condition of TiB.sub.2 and M boride. M denotes a metal.
