A dental implant capable of reliably preventing elution of metal when the dental implant is applied within an oral cavity and capable of reliably preventing occurrence of mismatching (bumpy occlusion or the like) when the dental implant is fixed in place. The abutment is manufactured by molding a ceramic molded body composition to obtain a ceramic molded body, assembling a titanium member and the ceramic molded body together to obtain an assembled body, degreasing the assembled body so that the ceramic molded body is transformed into a ceramic degreased body, and sintering the assembled body to transform the ceramic degreased body into a ceramic member so that the ceramic member is firmly fixed to the titanium member.
