Abstract

An aspect of the present invention relates to composite aggregate particles, which include a fine particle compound (a1) containing at least either an amorphous titanosilicate compound or an aluminosilicate compound, and a plastic powder (a2). The plastic powder (a2) is attached to at least a part of the surface of the fine particle compound (a1). The pore volume and the average particle size D50 of the composite aggregate particles satisfy the following formula: pore volume (ml/g)≥0.0010×D50 (μm)+1.60.
