A sheet for protecting a paint film which does not deteriorate or discolor the paint film even when the sheet is adhered to protect the paint film under the condition containing acidic rainwater or detergent and can maintain the adhered state over an extended-period of time without peeling off is disclosed. The sheet for protecting a paint film comprises a porous substrate and a pressure-sensitive adhesive layer formed on one surface of the porous substrate. The sheet has an air permeability in a direction of sheet thickness of 20,000 sec/100 cc or more and a moisture permeability in a direction of sheet thickness of 2,000 g/m ·24 hr or more. The sheet for protecting a paint film further comprises a porous substrate and a pressure-sensitive adhesive layer formed on one surface of the porous substrate, wherein the porous substrate has an ultraviolet transmission of 10% or less at a wavelength of from 190 to 370 nm.
