Abstract: Disclosed are a blood filter which exhibits excellent leukocyte elimination performance as well as significantly improved blood throughput per unit time and erythrocyte recovery rate and a method of manufacturing the same. The blood filter of the present invention includes a pre-treatment filter which is a laminate of first non-woven fabrics having a mean fiber diameter of 5 to 30 μm and a mean pore size of 10 to 30 μm, and a main filter which is a laminate of second non-woven fabrics having a mean fiber diameter of 1 to 5 μm, a mean pore size of 5 to 10 μm and a mean pore size distribution rate of 30% or more. A filling density of the pre-treatment filter and a filling density of the main filter, with respect to a target blood throughput of the blood filter, are 0.1 g/100 ml to 1 g/100 ml and 1 g/100 ml to 3 g/100 ml, respectively.
