Provided is a noise source search device to be applied to an MM apparatus that obtains an NMR signal generated from a subject disposed in a static magnetic field by applying an RF pulse of a high frequency coil and a gradient magnetic field pulse of a gradient magnetic field coil to the subject, the device including: a reference antenna and a probe antenna that measure a noise generated in the MRI apparatus; a noise generation condition specification unit that specifies an axis and a drive frequency as a noise generation condition generated in the MRI apparatus, on the basis of a noise intensity of the noise that is measured by the reference antenna; and a noise generation site specification unit that drives the gradient magnetic field coil under the noise generation condition that is specified by the noise generation condition specification unit.
