Abstract: In a method for producing composite particles containing polymer particles and silica particles that adhere to the polymer particles, the composite particles are obtained by subjecting a polymerizable monomer to aqueous suspension polymerization in a presence of silica particles and a cellulose compound adsorbing onto the silica particles. The composite particles contain the polymer particles, the silica particles that adhere to surfaces of the polymer particles, and the water-soluble cellulose compound.
