A method for manufacturing an artificial joint including a porous member and an artificial joint body, wherein the porous member made of a titanium material or a titanium alloy material is provided on an outer surface of a joint portion made of a titanium material or a titanium alloy material in the artificial joint body. Placed, and then the artificial joint body is placed in a metal tare and hermetically sealed under reduced pressure, and the metal tare is subjected to hot isostatic pressing under an inert atmosphere to form the porous member. A method is provided that includes diffusion bonding to the artificial joint body.多孔質部材と人工関節本体とを含む人工関節の製造方法であって、前記人工関節本体におけるチタン材料又はチタン合金材料からなる接合部の外面にチタン材料又はチタン合金材料からなる前記多孔質部材を配置し、次いで前記人工関節本体を金属風袋の中に入れて減圧下で密閉する密閉工程、及び前記金属風袋を不活性雰囲下で熱間等方圧加圧処理して前記多孔質部材を前記人工関節本体に拡散接合させる工程を含方法が提供される。
