To provide a sprayer with high safety, specifically, a sprayer from which a component to be sprayed is incombustible and which imposes less environmental burden. A sprayer comprising a container, a propellant composition containing 1-chloro-2,3,3,3-tetrafluoropropene contained in the interior of the container, and a spray unit to spray the propellant composition to the outside of the container, wherein the propellant composition to be sprayed satisfies (1) in a predetermined combustion test, the propellant composition to be sprayed is evaluated to “have no combustibility”, and (2) the global warming potential (100 years) in accordance with Intergovernmental Panel on Climate Change (IPCC), Fifth assessment report, is less than 10, throughout the entire period over which the sprayer is used.
