One aspect of the present invention is a composite agglomerate particle comprising a particulate compound (a1) consisting of an amorphous titanosilicate compound or an aluminosilicate compound, and a plastic powder (a2), wherein the plastic powder (a2) is the particulate compound ( It is attached to at least a part of the surface of a1), and it relates to a composite agglomerate particle, characterized in that the pore volume and average particle diameter D50 of the composite agglomerate particle satisfy the following equation. Pore volume (ml/g) ≥ 0.0010 × D50 (㎛) + 1.60 |
