PROBLEM TO BE SOLVED: To provide a plasma filtration unit capable of efficiently separating plasma and serum without leakage of blood cell components or hemolysis even with a very small amount of blood. The plasma filtration unit of the present invention comprises a blood filtration material in which at least a glass fiber filter paper and a microporous membrane are laminated, and a liquid impervious material. The plasma filtration unit is mounted on the surface of the microporous membrane. Comprising a member that has an opening narrower than the area of the membrane and restricts the flow-out area of the filtrate, and a blood filtration unit that includes at least two openings for containing these and a holder for containing the blood filtration material. is there.
