PURPOSE:To obtain filter cloth having high solid-liquid separation efficiency and a high self-recovery property relating to the clogging of a base material, by making the compressibility index of filter cloth, which is obtained by forming a raised filter layer of an extremely fine fiber formed by directly raising a fabric base material to said base material, constant in the thickness direction thereof. CONSTITUTION:The titled filter cloth is prepared by covering the surface of a fabric base material comprising a synthetic fiber such as a polyamide fiber with extremely fine fibers with a size of 0.1-10mum obtained by directly raising said base material to form a raised fiber filter layer and has a compressibility index of 0.3-0.65 in the thickness direction thereof. In use, said filter cloth is processed into an endless form and perforated belts are stitched to both ends in the lateral direction of the endless filter cloth so as to perform a left and right phase combination at the time of the running driving or running of the filter cloth.
