PROBLEM TO BE SOLVED: To provide a body fluid cleaning column which is free from residual materials such as solvent and fine powder harmful to human bodies, in which a bonding strength, air tightness, liquid tightness of a bonding part or others are high even though secondary injection molding is applied, and which can be safely used as a medical tool.SOLUTION: The body fluid cleaning column comprises a container body having a month (9, 9) of body fluid and a filling material (F) for cleaning the body fluid arranged in the counter the body. The container body is constituted by bonding a pair of half containers (A, B) shaped by primary injection molding at a bonding site (C) by the secondary injection molding. The bonding site (C) is located at the outer peripheral part of an abutting distal end part (T, T) of the bonding parts (At, Bt) obliquely extending so as to widen obliquely inward at an angle &thetas from the body parts (Ah, Bh).
