Abstract:
A method for inspecting a defect of a hollow fiber porous membrane having substantially uniform, continuous inner hollow portions comprises steps for introducing a part of the hollow fiber porous membrane into an irradiation chamber, for irradiating the hollow fiber porous membrane with light from the outside in the irradiation chamber, and for detecting light exiting the hollow fiber porous membrane on the outside of the irradiation chamber.
