PROBLEM TO BE SOLVED: To provide a rubber screen which includes a high attachment strength of a mounting fixture and can prevent the tension of a screen from becoming relaxed. SOLUTION: A rubber screen body 4 is formed by arranging a plurality of tensile bodies 1 each of which is covered with an elastic material 2 at prescribed intervals and providing opening parts 3 for screen among the tensile bodies 1. A plurality of insertion holes 6 are bored through the mounting fixture 5 attached to a vibration screening machine. The tensile body 1 is inserted through the mounting fixture 5 by passing an end part of the tensile body 1 which is exposed from the elastic material 2, through one insertion hole 6 of the mounting fixture 5 and passing the end part of the tensile body 1 through another insertion hole 6 by folding back and bending the tensile body 1. The mounting fixture 5 is covered with a cover layer 7 and the tensile body 1 of a part which passes through the insertion hole 6 is buried in the cover layer 7. A tensile force applied to the tensile body 1 is received by parts where the tensile body 1 is folded back and bent and, thereby, is passed through the insertion hole 6 and, as the result, the mounting fixture 5 can be attached to the rubber screen body 4 with a high strength in a state where the action of tensile force for an adhesion part between the cover layer 7 and the tensile body 1 is reduced.
