To enhance the bending strength of a panel around the axes parallel and vertical to the plane thereof by constituting two half panels of skins and a plurality of webs arranged vertically to the inside surfaces of the skins to integrally mold them along with the skins and mutually bonding the skins through the webs as the planar place arranged between the skins.
A panel 10 is constituted of an upper half panel 12 and a lower half panel 14 and two half panels 12, 14 are equipped with outside surfaces or skins 18 and a plurality of webs or ribs 20 arranged vertically to the inside surfaces of the skins 18 and integrally molded along with the skins 18. The two half panels 12, 14 are mutually bonded through the webs 20 at the place of the plane 16 arranged between the skins 18. By this constitution, the panel 10 has strength such as bending strength or compression strength around all axes parallel to the plane of the panel and the axis vertical to the plane of the panel 10.
