The present inventions provide manufacturing methods of 1,1,1,2,3-pentafluoropropene characterized by the reaction of removing HF by means of the contact of 1,1,1,2,3,3-hexafluoropropane in the gas state with active carbon or active carbon added with metallic salt. 1,1,1,2,3- pentafluoropropene can be produced from easily available 1,1,1,2,3,3-hexafluoropropane by cost-effective industrial methods at high yields according to these inventions. The inventions also provide manufacturing methods of 1,1,1,2,3-pentafluoropropane characterized by reducing 1,1,1,2,3-pentafluoropropene with hydrogen under the presence of a hydrogenation catalyst consisting of palladium added with one or more of silver, copper, gold, tellurium, zinc, chromium, molybdenum, and thallium or under the presence of a rhodium catalyst. The desired product can be produced at high reactivities and high selectivities according to these inventions.
