[PROBLEMS] To achieve excellent durability and peelability. Even if a coating layer is provided on the surface, peeling of the coating layer is reliably prevented. In a tablet punch or mortar, a tableting surface layer 5 contains a hard metal different from the base metal in addition to the base metal, and the content of the hard metal is compressed from the base material. It becomes higher toward the surface layer 5. This hardened metal contains at least one of W, C, B, Ti, N, and Cr. Furthermore, the tablet punch or mortar of the tablet has Ra (surface arithmetic average roughness) of the tablet surface layer 5 of 0.1 μm or more and 5 μm or less. [Selection] Figure 1 |
