A sintered body which contains at least cobalt as a metal and is composed of boron and/or at least one metal selected from platinum group elements or an alloy of the metal and an oxide, said sintered body being characterized in that at least one compound selected from Cr(BO3), Co2B2O5 and Co3B2O6 is contained in a phase composed of the oxide. A sintered body in which a compound selected from Cr(BO3), Co2B2O5 and Co3B2O6 is present in a target can maintain a fine structure, and enables the provision of a sintered body for magnetic recording film formation use which comprises a sintered body that is stable in water. |
