PROBLEM TO BE SOLVED: To provide a multi-layer resin molding which is constituted of a resin containing a plant origin resin, and at the same time, has durability by suppressing the hydrolysis. SOLUTION: In this multi-layer resin molding, a surface layer covers the periphery of a base layer. In the multi-layer resin molding, the surface layer 11 is constituted of a non-plant origin resin, and the base layer 21 is constituted of an alloy resin of the plant origin resin and the non-plant origin resin of the surface layer 11. Thus, the using amount of a petroleum origin resin, which is the non-plant origin resin, is reduced, and at the same time, the moisture in the atmosphere or the like is prevented from entering the base layer 21 by the surface layer 11 made of the non-plant origin resin, and the hydrolysis of the plant origin resin in the base layer 21 is suppressed to improve the durability. Therefore, the multi-layer resin molded body which is suitable as an automobile interior member, for which the reduction of the using amount of the petroleum origin resin is required, and at the same time, durability is required as well, is obtained.
