PROBLEM TO BE SOLVED: To provide a novel implant for medical use, having excellent cell adhesion property or the like.SOLUTION: In an implant for medical use carrying ceramic particles, particle diameters of the ceramic particles are in the range of 10-700 nm, the ceramic particles are sintered particles of calcium phosphate, and the ceramic particles do not contain calcium carbonate. In the implant for medical use, the maximum diameter of the short axis in the particle diameters of the ceramic particles is 30 nm to 5 μm, the maximum diameter of the long axis therein is 75 nm to 10 μm, and the implant for medical use is configured with the sintered particles of calcium phosphate growing in the c axis direction and having an aspect ratio ((c axis length)/(a axis length)) of the crystal is 1-30.SELECTED DRAWING: None 【課題】細胞密着性等に優れた、新規な医療用インプラントの提供。【解決手段】セラミック粒子を担持した医療用インプラントにおいて、前記セラミック粒子の粒子径が、１０〜７００ｎｍの範囲内であり、前記セラミック粒子が、リン酸カルシウム焼結体粒子であり、前記セラミック粒子が、炭酸カルシウムを含有しない医療用インプラント。セラミック粒子の粒子径が短軸の最大値径が３０ｎｍ〜５μｍであり、長軸が７５ｎｍ〜１０μｍであり、ｃ軸方向に成長し、結晶のアスペクト比（ｃ軸長／ａ軸長）が１〜３０である、リン酸カルシウム焼結体粒子からなる医療用インプラント。【選択図】なし
