Abstract

A cermet () includes a bonding phase () and a hard phase (). The hard phase () includes: a first hard phase () composed of TiCN; and a second hard phase () composed of a composite carbonitride of Ti, which is greater than the average particle diameter of the first hard phase (). The cermet () further includes an aggregate part () formed by interlinking parts of the second hard phase (). The second hard phase () forming the aggregate part () includes a 2a-th hard phase () having a maximum W content of an inner part thereof that is more than 1.1 times as great as an average W content of an outer circumferential part thereof, in terms of mass ratio. The aggregate part () composes a proportion of from 20% to 60% of the cermet () in terms of surface area.
