PURPOSE: A sensor for damage of hollow-fiber membrane is provided to easily catch damage of the hollow-fiber membrane through oscillation frequency. CONSTITUTION: A sensor for damage of a hollow-fiber membrane comprises: a separator unit having plural hollow-fiber membrane module(10) comprising hollow-fiber(13) bunch; an air compressor(20) which is able to inject pressurized air; a sensing part(30) which senses oscillation frequency; and a controller(40) which receives frequency signal of each sensing part and monitors damage of the hollow-fiber.
