Abstract

The present invention provides porous particles made of an organic polymer, uniform in shape, and having through holes that are not closed. The porous particles according to the present invention are porous particles having a substantially spherical shape. The porous particles are made of an organic polymer. Each of the porous particles has an interconnected pore structure in which through holes provided inside the porous particle communicate with each other, and ends of the through holes are open toward an outside of the porous particle.
