Abstract

The present invention relates to a hydroxyapatite-supporting porous silica particle, in which hydroxyapatite is supported on a surface a spherical porous silica particle and inner surfaces of pores of the spherical porous silica particle, and in which the hydroxyapatite-supporting porous silica particle has a circularity of 0.760 or larger, a method for producing the hydroxyapatite-supporting porous silica particles, and a composition containing the hydroxyapatite-supporting porous silica particle.
