Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vehicle fender liner capable of: exerting icing prevention properties from both front and back faces of the fender liner; showing high sound absorption properties; and being easily molded in a three-dimensional shape.SOLUTION: A fender liner used for a vehicle exterior sound absorption material includes a base material layer 11 having a sound absorption function. The base material layer 11 is produced by forming a sheet made of a fiber web in which main fiber 12 and binder fiber 13 having a lower melting point than the main fiber 12 are entangled. On the sheet-shaped web, a first protective film 15 made of a low density polyethylene (LDPE) resin is integrally formed, and on top of the other side of the sheet, a second protective film 17 made of a thermoplastic resin film is placed before applying heat and pressure by using a plate-shaped press die, forming a laminate sheet in which the air-impermeable first protective film 15 and the air-permeable/liquid-impermeable second protective film 17 are integrally formed on the base material layer 11. Then the laminate sheet is heat press molded by using a molding die to form a three-dimensional shape of a fender liner 10.
