PROBLEM TO BE SOLVED: To reduce cost of a resin cover material, to mold the base material by using a resin material composed of inexpensive polypropylene resin having preferable molding property as a main component, and to firmly fuse the cover material and the base material together to integrate them, in manufacturing an automobile interior panel. SOLUTION: The manufacturing method of the automobile interior panel includes: cover material molding processes (b), (c) of molding the resin cover material; a primer treatment process (d) of forming the primer coating on the rear face of the cover material obtained in the cover material molding processes by primer 14 containing modified olefin resin; and integration molding processes (e)-(g) of molding the base material by a molten resin material R having polypropylene resin as the main component on the primer coating side of the cover material subjected to the primer treatment in the primer treatment process, and of integrating the cover material with the base material across the primer coating.
