PURPOSE: A circuit for eliminating noise of oscillation frequency is provided to reduce an electro magnetic interference noise by eliminating noise due to the harmony components of the oscillation frequency. CONSTITUTION: A circuit for eliminating noise of oscillation frequency includes an oscillation circuit(10) providing a base oscillation frequency, a plurality of IC(20,30) operating according to the oscillation frequency of the oscillation circuit(10), a spread circuit(25) for suppressing the generation of the peak energy by spreading the base oscillation frequency in a constant ratio and providing the IC(20,30) respectively with an oscillation frequency.
