Implant

[Subject] An implant is equipped with the surface which reduced powerfully activation of the blood condensation accompanied by formation of biofilm, and formation of a thrombus. [Means for Solution] An implant substrate is an implant, wherein the coat is carried out in a thin layer of a charge of a coating material, In 2 to 45% of volume, a size (0.4 nm), [in / including a compound of one or more sorts of metal (M) of IV A fellows of a periodic system, nitrogen (N), and oxygen (O) / in the charge of a coating material / the charge of a coating material] 3 - (50 nm) 3 It is formed of Boyd of の範囲, remainder volume consists of a constituent whose metal: nitrogen: oxygen of IV A fellows of a periodic system is 1: (0.1-1.7) : (0.1-1.7), and it is formula MN. X O y An implant being the material which has (inside x of a formula and y= 0.1-1.7) is solved. [Chosen drawing] Drawing 1
