PROBLEM TO BE SOLVED: To make it possible to greatly simplify a bonding process between a skin material and a molded product for manufacturing an automobile interior material, the precoated adhesive surface is non-adhesive and requires release paper. To provide a hot-melt adhesive which can be formed and bonded without heating a molded product and which is excellent in heat resistance used for a pre-coated skin material for an automobile interior, and a method for producing an automobile interior material using the pre-coated skin material It is in. SOLUTION: An amorphous poly (α-olefin) (A) having a melt viscosity in the range of 500 to 100,000 mPa · s / 190 ° C., and a tackifier resin (B) having a softening point of 110 ° C. or higher by a ring and ball method (B) And a hot-melt adhesive containing a polypropylene wax (C) having a melting point of 120 ° C. or more as an essential component and a weight ratio of (A) to (C) of 100/50 to 100/100, And a pre-coated skin material for automobile interiors, which is preliminarily applied to a vehicle.
