Abstract: The disclosure provides a production method capable of producing a hollow fine particulate containing a fluorine-containing resin and having a large average particle size. The production method includes a step A of dispersing a solution containing a fluorinated monomer and a non-polymerizable solvent into water to provide a dispersion; a step B of polymerizing the fluorinated monomer to provide a phase-separated fine particulate containing a fluorine-containing resin; and a step C of removing the non-polymerizable solvent in the phase-separated fine particulate to provide a hollow fine particulate.
