To provide a method for producing an interior finish material using a two-tone spray skin material which has no parting groove in the joint part of the skin material and demonstrates excellent disignability.
In the method for producing the interior finish material using the spray skin material, a resin is injected on the back side of the spray skin material 1 to make a skin-integrated interior finish material. The spray skin material 1 is made the two-tone spray skin material comprising a first color skin material 1a and a second color skin material 1b. A parting groove 2 having a U-shaped cross section is formed in the joint part. A deformed skin part 3 is formed in the second color skin material 1a of the parting groove 2. By deforming the deformed skin part 3 to be contacted with a groove opening part corner 2b on the side of the second color skin material, the parting groove 2 is closed.
