PROBLEM TO BE SOLVED: To provide a manufacturing method, by which reduction in machining man-hours, prevention of separation between layers, and improvement in sound absorbing performance are accomplished, for an automobile interior part constructed of a lamination body consisting of a sound absorbing nonwoven fabric base material and a coating material. SOLUTION: After a coating material consisting of a cloth 21 and a nonwoven fabric 22 and a sound absorbing nonwoven fabric base material 30 are integrated together by needle punching, they are heated so as to be softened, and then, molded into a required shape by cold pressing molding. Therefore, a conventionally used film type hot melt adhesive is done away with, so that adhesion strength and sound absorbing performance can be improved while simplification of material constitution and reduction in man-hours can be accomplished.
