PROBLEM TO BE SOLVED: To provide a porous particle which is of the order of micron, porous and a monodisperse and has a narrow particle size distribution. SOLUTION: The manufacturing process of the porous monodisperse particle comprises using, for the seed particle, an acrylic resin particle containing≥70 mass% of polymethyl methacrylate or methyl methacrylate for a copolymerizing component, swelling the resin particle to 20-80 times the seed particle by mass with a swelling liquid containing a monomer mixture containing≥70 mass% of methyl methacrylate and 3-8 mass% of vinylbenzene and an oil-soluble polymerization initiator and polymerizing the monomer mixture.
