<p>Disclosed is a cermet excellent in thermal shock resistance and fracture resistance. Specifically disclosed is a cermet (1) which is obtained by binding hard particles (2) with a binder phase (3) which is composed of at least one of Co and Ni. The hard particles (2) are composed of one or more of carbides, nitrides and carbonitrides of one or more metals selected from group 4, 5 and 6 metals of the periodic table. In this cermet (1), there exists a joint portion (6) wherein the hard particles (2) are joined together through a binder phase layer (5) having a thickness of 0.1-3 nm, thereby forming a neck portion (4).</p> |
