Abstract

Disclosed is an automobile body undercover having durability against damage from foreign objects such as flying stones even in a case where a nonwoven fabric is used on an outer surface on a road surface side in order to achieve sound absorbing characteristics with respect to engine noise leaked outside a car, road noise originating from the road surface side, or the like. The automobile body undercover includes at least: a base material layer (11) that includes a mixture of a fiber reinforcing material and a first thermoplastic synthetic resin (13); and a nonwoven fabric layer (15) of a thermoplastic synthetic fiber that is stacked on a surface that is a road surface side of the base material layer (11), surface portions of both the layers being bonded by thermal fusion, and both the layers being compression-molded into a predetermined shape to form a fiber molded body, wherein the first thermoplastic synthetic resin (13) of the base material layer (11) has a melting point for melting in a heating process at the time of molding, and wherein the nonwoven fabric layer (15) includes a mixture of a second thermoplastic synthetic fiber (16) having a melting point for melting in the heating process at the time of molding and a third thermoplastic synthetic fiber (17) having a melting point for non-melting in the heating process at the time of molding.
