The purpose of the present invention is to provide an antimicrobial material and an implant with which it is possible to sustain antimicrobial properties over an extended period of time. The above problem can be solved by this silver-containing calcium phosphate sintered body including silver particles in the interior, wherein the average particle size of the silver particles in the silver-containing calcium phosphate sintered body is 0.01-0.5 μm. L'objet de la présente invention est de pourvoir à un matériau antimicrobien et à un implant qui permettent de conserver des propriétés antimicrobiennes sur une période de temps prolongée. La solution selon l'invention porte sur un corps fritté en phosphate de calcium contenant de l'argent y compris des particules d'argent, la granulométrie moyenne des particules d'argent dans le corps fritté en phosphate de calcium contenant de l'argent étant de 0,01 à 0,5 µm. 本発明の目的は、長期にわたって、抗菌性を持続することのできる抗菌性材料及びインプラント体を提供することである。　前記課題は、本発明の銀粒子を内部に含む銀含有リン酸カルシウム焼結体であって、前記銀粒子の平均粒子径が０．０１～０．５μｍである銀含有リン酸カルシウム焼結体によって解決することができる。
