<P>PROBLEM TO BE SOLVED: To provide a resin laminated plate which ensures reduction of weight and thickness, and increases more rigidity. <P>SOLUTION: The resin laminated plate 100 includes a front face-side sheet 120A and a back face-side sheet 120B that are overlapped each other with a hollow part therebetween. Here, the back face-side sheet 120B is dented into the hollow part to provide a plurality of first and second dent parts 200S and 200L, and the bottoms of the plurality of first and second dent parts 200S and 200L are welded to the front face-side sheet 120A to connect between the front face-side sheet 120A and the back face-side sheet 120B through a plurality of ribs. The resin laminated plate 100 is composed of: a thin plate part 100a having a plurality of first dent parts 200S, the depth of which being shallow; and a thick plate part 100b having a plurality of second dent parts 200L, the depth of which being deep. In addition, the plurality of first and second dent parts 200S and 200L are arranged at almost the same pitch. <P>COPYRIGHT: (C)2013,JPO&INPIT |
