ができ、作業能率を向上させることができる。According to the method of molding an interior material for a vehicle of the present invention, a low melting point adhesive film that melts at a temperature at which the interior base material can be formed is laminated on the surface side of the interior base material to form the interior base material. A high melting point adhesive film having a melting point higher than the moldable temperature of the interior base material is laminated on the back side, and the low melting point adhesive film is heated and melted, and then a skin material is laminated on the low melting point adhesive film. Cold press molding was performed, and then the high melting point adhesive film was heated and melted to join the clip seats, so the air permeability of the interior base material can be prevented, and the glass fibers on the surface of the interior base material may be scattered. Without this, the clip seat can be simply and quickly joined to the back surface side of the interior base material, and the work efficiency can be improved.
