A joined article 1 in which a first metal member 2 made of a tungsten carbide base cemented carbide and a second metal member 3 made of a martensitic stainless steel having a carbon equivalent of 2.5 to 3.5 and containing 0.030 mass % or less of sulfur are joined. The martensitic stainless steel having the carbon equivalent of 2.5 to 3.5 is preferably at least one selected from the group consisting of SUS431, SUS420J1, SUS420J2, SUS410, SUS410J1, S-STAR, PROVA-400, HPM38, STAVAX ESR, and SUS403 in the joined article 1. There is disclosed a joined article in which the lowering of the strength of a second metal member around a joining interface thereof is prevented.
