To provide a new dispersion of porous fine particles which is a dispersion of porous fine particles in a dispersing medium, free from problem on porous fine particles, excellent in long time storage.
The dispersion of porous fine particles comprises porous fine particles dispersed in the dispersing medium wherein the dispersion satisfies following relation, 50/(1.8+TPV)≤C≤100/(1.8+TPV), in the relation TPV (ml/g) is pore volume of the porous fine particles and C (wt.%.) is the concentration of the porous fine particles in the dispersion. The dispersion of porous fine particles without forming precipitation of the porous fine particles, excellent in storage stability is obtained by setting the concentration of the solid content depending on the pore volume of the porous particles.
