An invention being applied is a defect detecting apparatus that has: an illuminating optical system with a laser light source for irradiating a sample on whose surface a pattern is formed with light; a detecting optical system with a sensor for detecting light generated from the sample illuminated by the illuminating optical system; and a signal processing unit that extracts a defect from an image based on the light detected by the detecting optical system, in which an amplification rate of the sensor is dynamically changed during a time when the light is detected by the detecting optical system.. .
