To solve problems that a conventional converter is constituted to have a wire-coil and, when a current flows in the wire-coil, a magnetic field is formed, and the magnetic field disturbs a static magnetic field formed by a magnet of an MR imaging apparatus and becomes a cause of a noise when collecting MR signals.

This oscillating device 100 is provided with a receiving part 101 receiving electric signals, a signal generating part 102 generating and outputting a voltage of a predetermined frequency and a predetermined waveform synchronous with the electric signals received by the receiving part 101, an oscillation generating part 103 receiving the voltage of the predetermined frequency and the predetermined waveform generated by the signal generating part 102 and generating the oscillation based on the voltage of the predetermined frequency and the predetermined waveform, an oscillation transmission part 103 contacted with the oscillation generating part 103 and transmitting the oscillation generated by the oscillation generating part to an object 200, and a fixing support part 104 fixing and supporting a predetermined position of the oscillation transmission part 103.
