PROBLEM TO BE SOLVED: To provide a manufacturing method of a foamed laminated sheet for a car trim material excellent in dimensional stability, lightweightness, rigidity and molding processability and enabling inexpensive manufacturing processability and quality stability, and the car trim material using the foamed laminated sheet. SOLUTION: The foamed laminated sheet for the car trim material is constituted by laminating non-foamed layers comprising a non-crystalline thermoplastic resin to both sides of a foamed layer comprising a heat-resistant resin being a base material resin. In the manufacturing method of the foamed laminated sheet, an organic fiber nonwoven fabric and a crystalline thermoplastic resin film layer overlie at least one of the non-foamed layers comprising the non-crystalline thermoplastic resin and a repulsive elastic roll is used as at least one of pressure holding rolls in the process of laminating the organic fiber nonwoven fabric on the non-foamed layers by an extrusion lamination method to continuously and consistently form the laminate of the organic fiber nonwoven fabric and the non-foamed layers while keeping the extrusion molten state of the non-foamed layers.
