  A method for producing tetrafluoromethane as follows is unlikely to damage a reaction apparatus and can produce tetrafluoromethane safely, inexpensively, and stably. To a raw material liquid containing a fluorinated hydrocarbon represented by chemical formula C p H q Cl r F s (wherein p is an integer of 3 to 18, q is an integer of 0 to 3, r is an integer of 0 to 9, and s is an integer of 5 to 30) and having no carbon-carbon unsaturated bond, fluorine gas is introduced, and concurrently a reaction inducer is introduced in a gas state, giving tetrafluoromethane. The reaction inducer is reacted with fluorine gas to induce a reaction of forming tetrafluoromethane from the fluorinated hydrocarbon and the fluorine gas and is at least one reaction inducer selected from a hydrocarbon gaseous at normal temperature and pressure and hydrogen gas.
