PROBLEM TO BE SOLVED: To provide a monodisperse porous resin particle excellent in solvent resistance, its manufacturing method, and use thereof.SOLUTION: The porous resin particle consists of a crosslinked polymer containing a structural unit derived from a crosslinked polymer having two or more ethylenically unsaturated group, and a structural unit derived from a monofunctional (meth)acrylic monomer having an ethylenically unsaturated group. The content of the structural unit derived from the crosslinked monomer is 18 to 89 wt.% based on the total amount of the crosslinked polymer, a specific surface area is 0.4 m/g or more and less than 2.0 m/g, the amount of an elution component is 1 to 10 wt.% or more, a variation coefficient of particle size is 15% or less and a volume average particle is 10 to 100 μm. |
