A porous resin aggregate capable of efficiently adsorbing and removing siloxanes, a siloxane remover, and a gas sensor filter are provided. SOLUTION: Aggregating porous resin particles having a crosslinked structure formed by polymerization of a monofunctional aromatic vinyl monomer (such as styrene) and a polyfunctional aromatic vinyl monomer (such as divinylbenzene). To obtain an aggregate. This aggregate efficiently adsorbs cyclic siloxanes [cyclic trimer (D3), cyclic tetramer (D4), cyclic pentamer (D5), etc. of siloxane]]. [Selection] Figure 1 |
