    摘要: A leukocyte-removing filter material is described, which includes a porous element having fine pores of an average pore diameter of not less than 1.0 .mu.m but less than 100 .mu.m and a fiber structure composed of a plurality of fibers having an average fiber diameter of not less than 0.01 .mu.m but less than 1.0 .mu.m kept on the porous element. The porosity of the filter material is not less than 50% but less than 95%, and the proportion of the fiber structure to the filter material is not less than 0.01% by weight but less than 30% by weight. The ratio between the average pore diameter of the porous element and the average fiber diameter of the fiber structure is not less than 2 but less than 2,000 and the above fiber structure forms a reticulate structure. A process for producing the leukocyte-removing fiber material and an apparatus for removing leukocyte using the above fiber material are also described.
