RESIN PANEL AND FORMING METHOD

摘要

The present invention provides a resin panel of which contact surfaces of a rear wall to be in contact with another member are made unlikely to deform while reducing the weight of the resin panel. A resin panel (1) according to the present invention includes a rear wall (3) having a plurality of contact surfaces (31) to be in contact with another member (not shown), and a front wall (2) opposing the rear wall (3) with an interval therebetween, the resin panel including a plurality of ribs (3a) obtained by indenting parts of the rear wall (3) toward the front wall (2) and welding the parts to an inner surface of the front wall (2), wherein a wall thickness of the front wall (2) is generally equal to or smaller than a wall thickness of the rear wall (3).
