An antibacterial member capable of maintaining high antibacterial properties and high osteoconductivity for a long period of time is provided. The antibacterial member of the present invention is provided with a DLC film (F-DLC film) 40 containing fluorine on at least a part or the whole of the outermost surface of the substrate 10, and the element ratio (F / F) of the F-DLC film + C) is 17% to 72%, and the nanoindentation hardness is 2,000 MPa to 16,000 MPa. Thereby, abrasion resistance and adhesiveness can be maintained, and an antibacterial member maintaining high antibacterial property and high osteoconductivity for a long time can be obtained. The F-DLC film does not necessarily have to cover the entire outermost surface of the base material, and may be arranged in a patch shape.高い抗菌性と高い骨伝導性を長期間維持できる抗菌性部材を提供する。 本発明の抗菌性部材は、基材10の最表面の少なくとも一部又は全体にフッ素を含むDLC膜（F－DLC膜）40を備えており、前記F－DLC膜の元素比(F／F+C)が17％～72％、且つナノインデンテーション硬さが2,000MPa～16,000MPaであることを特徴とする。これにより、耐摩耗性と密着性を維持でき、高い抗菌性と高い骨伝導性を長期間維持した抗菌性部材を得られる。F－DLC膜は必ずしも基材の最表面全体を覆っている必要はなく、斑状に配置してもよい。
