PROBLEM TO BE SOLVED: To provide an inclined plate for a settling apparatus, which is easily recycled and has satisfied rigidity, formability, impact resistance and the like. SOLUTION: The inclined plate for the settling apparatus is obtained by applying a rib structure to a hard plate composed of a polyester based resin composition consisting essentially of a weak crystalline or non-crystalline polyester based resin and having 0.8-2.5 mm thickness by a vacuum and/or pressure forming to increase the rigidity and a polyester based resin having 0-6 cal/g heat of fusion of crystal by the DSC method (JIS K7121) is used particularly as the weak crystalline or amorphous polyester based resin. |
