<p>The present invention relates to an apparatus for detecting defects using a multi magnetic sensor. According to the invention, the invention comprises a power supply unit, a sensor module which outputs sensing power corresponding to a magnetic field of an object to be detected by receiving input power from the power supply unit; and a signal receive unit which calculates intensity distribution of the magnetic field by converting the sensing power outputted from the sensor module into a quantitative numerical value. The sensor module is horizontally overlapped on first and second sensor arrays which detect magnetic vectors vertical to a sensor surface, and provides device for detecting defects including the second array which detects the magnetic vectors horizontal to the sensor surface. The apparatus for detecting defects is capable of detecting magnetic field distribution horizontally and vertically formed to the sensor surface, and increasing the degree of integration by reducing external wires of the sensor arrays.
