PROBLEM TO BE SOLVED: To provide a leukocyte removal filter where efficiency of filtration work is improved by the reduction of a filtration time and blood is collected with high yield without degrading performance of leukocyte removal when performing a filtration method of pouring the blood into the leukocyte removal filter consisting of a flexible container by gravity difference. SOLUTION: The leukocyte removal filter comprises the flexible container having the entrance and exit of the blood and a sheet-like a leukocyte removal filter material arranged so as to divide the inside of the container into an entrance side and an exit side.
