Provided is a production method capable of producing hollow fine particles which contain a fluorine-containing resin and have a large average particle diameter. This method for producing hollow fine particles containing a fluorine-containing resin is characterized by comprising a step A in which a solution containing a fluorine-containing monomer, an oil-soluble initiator, and a non-polymerizable solvent is dispersed in water including a fluorine-containing surfactant, and the fluorine-containing monomer is polymerized to obtain hollow fine particles. 本发明提供能够制造包含含氟树脂、平均粒径大的中空微粒的制造方法。一种中空微粒的制造方法，其是包含含氟树脂的中空微粒的制造方法，其特征在于，该方法包括工序A，该工序A中，将包含含氟单体、油溶性引发剂和非聚合性溶剂的溶液分散在包含含氟表面活性剂的水中，使上述含氟单体聚合而得到中空微粒。
