The present application provides a method for producing hydrofluoroolefin (HFO) or fluoroolefin (FO), which does not require high temperature and catalyst in the synthesis process of the target compound, and has a high selectivity of the target compound.nSpecifically, the present case provides a method for producing hydrofluoroolefins or fluoroolefins, which is a method for producing hydrofluoroolefins or fluoroolefins with carbon numbers of 2, 3 or 4, characterized in that: At least one raw material compound in the group consisting of hydrofluorocarbons and hydrofluoroolefins A with 2 or 3 carbon atoms is irradiated with ionizing radiation and/or ultraviolet rays with a wavelength of 300 nm or less (however, when the above-mentioned raw material compounds are the above-mentioned hydrofluoroolefins A , the obtained aforementioned HFO is different from the aforementioned HFO A). |
