PROBLEM TO BE SOLVED: To reduce reduction in the effective filtering film area caused by a capillary phenomenon, and eliminate the occurrence of external appearance failure by arranging a means to diametrically contract an outside diameter of a hollow thread bundle more than an inside diameter of a filtering part housing, in a seal part to fix at least one end of a hollow thread in a close contact condition. SOLUTION: An infusion inflow port 5 and an infusion outflow port 6 are formed on a surface where a housing main body 2 and cover materials 3 and 4 are opposed to each other. The housing main body 2 is composed of a seal part 2A of an end part on which the cover material 4 is installed and a filtering part 2B of its upper position. The filtering part 2B is composed of a hollow thread bundle 9 fixed in a condition of penetrating through a sealing part 2A material. A housing inside diameter of the seal part 2A is diametrically contracted more than that of the filtering part 2B, and the hollow thread bundle 9 inserted from one end of a cylindrical housing main body 2 is gripped at an interval of a degree that a seal material flows in the diametrically contracted seal part 2A. |
