Abstract: An interior finishing panel for a vehicle, comprising a first wall) and a second wall opposed to each other at an interval. The panel is formed in a hollow double wall structure having an inner rib formed between the first wall and the second wall. A skin sheet with an averaged thickness of 2.0 mm or thinner is integrally laminated on the first wall. The skin sheet is formed in a double layer structure in which a nonwoven cloth with a weight of 250 g/m<2> or less is stuck on a resin sheet, and its tensile elastic modulus at room temperature is 3500 kg/cm<2> or less. A parting line and a step part are formed on a peripheral wall within the range of 35% of the averaged thickness of the panel from the first wall side over roughly all the periphery thereof, and the end of the skin sheet is melt-bonded to the peripheral wall along the step part. A three-dimensional pattern is produced on the surface of the resin sheet forming the skin sheet.
