PROBLEM TO BE SOLVED: To separate a solid component of blood from a liquid component thereof, by allowing an operation for a micro amount of fluid while simplifying constitution, by mixing a coagulant, or a flocculation promotor in some cases, into the blood, and by precipitating a generated agglutination block by a flow structure. SOLUTION: This flow passage having driving force for operating the fluid is proposed without using an external driving source, a hemocyte component of the blood is flocculated with the coagulant or the like having no hemolysis ability, and the solid component of the blood is separated simply, quickly, and easily from the liquid component thereof, by the structure having a deceleration weir, a precipitation step difference, a diagonally upward flow passage, a flow passage with a cross section reduced gradually or the like, which are provided in the flow passage.
