The purpose of the present invention is to provide a porous polyethylene hollow-fiber membrane which uses a resin composition containing polyethylene and having excellent fluidity, and which retains excellent film quality and stiffness, and has high permeability and excellent filtering characteristics, and also to provide a hollow-fiber membrane module and a water purifier cartridge equipped with the porous polyethylene hollow-fiber membrane. The porous polyethylene hollow-fiber membrane is formed from a resin composition which contains polyethylene and has excellent fluidity, and the average pore-diameter in the hollow-fiber membrane is 0.1-0.5µm; the pore-diameter distribution in a region ± 0.05 µm from the average pore-diameter is at least 70% of the total pore-diameter distribution; the metal flow rate measured in accordance with JIS K7210 code D is 0.1-0.9g/10 minutes, and the metal flow rate measured in accordance with code G is 50-100g/10 minutes, with the FRR ratio (G/D) thereof being 50-100; and the density is 0.962-0.968g/cm3. Also provided are a hollow-fiber membrane module and a water purifier cartridge equipped with the porous polyethylene hollow-fiber membrane |
