摘要： Provided is an inspection method of a hollow fiber membrane module and a repairing method capable of quickly identifying the position of a damaged membrane in the hollow fiber membrane module with a simple configuration. An inspection method of a hollow fiber membrane module (1) of the invention includes: a step of covering a potting end surface (8) at which an opening end of hollow fiber membranes (2) of a hollow fiber membrane bundle (4) is open with a light-transmissive cap (10) to form a sealed space; a step of reducing a pressure of the sealed space in a state where an inner portion of the hollow fiber membrane is filled with a liquid and an outer portion of the hollow fiber membrane comes into contact with air; a step of detecting bubbles released from the potting end surface; a step of illuminating the potting end surface with two line-shaped light beams (14, 16) which are longer than a diameter of the potting end surface through the light-transmissive cap so as to intersect at a position where the bubbles of the potting end surface are detected; a step of identifying a position of the damaged hollow fiber membrane on the potting end surface using an intersection (19) of the two line-shaped light beams; and a step of performing leakage prevention on the damaged hollow fiber membrane.
