(JA) The invention is to provide a porous film excellent in barrier properties, such as blood barrier property and viral barrier property, puncture strength, and moisture permeability. It is also a task to provide a waterproof and moisture-permeable material that uses the porous film excellent in barrier properties, such as blood barrier property and viral barrier property, and reduces the stuffing feeling that a person feels when wearing it and is excellent in the wearing comfortableness. The foregoing tasks are achieved by a porous film whose degree of moisture permeability is greater than or equal to 150 g/m 2 ·h, and whose puncture strength is greater than or equal to 100 N/mm, and whose blood barrier property is class 4 or higher, a porous film whose degree of moisture permeability greater than or equal to 150 g/m 2 ·h, and whose puncture strength is greater than or equal to 100 N/mm, and whose viral barrier property is class 3 or higher, or a porous film whose degree of moisture permeability is greater than or equal to 150 g/m 2 ·h, and whose puncture strength is greater than or equal to 100 N/mm, and whose blood barrier property is class 4 or higher, and whose viral barrier property is class 3 or higher. |
