PURPOSE: To make the above composite a rubber-conductive fiber composite useful as a shielding material which is flexible and possesses favorable shielding properties against an electromagnetic wave.

CONSTITUTION: A conductive fiber to be mixed into rubber in a rubber- conductive fiber composite is mixed into the rubber-conductive fiber composite so that a lengthwise direction, widthwise direction (circumferential direction) and thicknesswise direction turn respectively orientation directions each and a rate of capacity of a conductive fiber having the lengthwise direction for its orientation direction to be held in capacity of the whole conductive fiber is set up at not exceeding 33%. With this constitution, the bending modulus of elasticity of the rubber-conductive fiber composite is lowered and a flexible sheetlike body or a roll-like body is obtained.
