Abstract: There is provided a method of producing a plastic optical component from a plastic material using an injection molding machine. This method removes foreign matter from a molten plastic material having dissolved therein 0.1 mass % or more of carbon dioxide through a filter arranged midway through a passage for the molten plastic material provided in the injection molding machine and injects the molten plastic material into a molding die preliminarily pressurized with a pressurization gas to prevent foaming of the molten plastic material. Even when a high filtration precision filter is provided in the injection molding machine, the filtration pressure loss is low and there is no breakage of a filter. It is also possible to significantly reduce the fraction defective of plastic optical components due to contamination by foreign matter or clouding resulting from foaming of carbon dioxide.
