PURPOSE: An apparatus is provided to intercept electromagnetic wave of a wiper motor, and to prevent failed operation caused by the noise generated in the driving of the wiper motor. CONSTITUTION: A condenser(C1-C5) of an apparatus for intercepting electromagnetic wave of a wiper motor is connected to all terminals of the motor, and is connected to a high terminal and a low terminal together with a ground line. A coil(L1-L2) is connected to the several high terminals and low terminals in series for removing a resonance frequency of electromagnetic wave noise at the output terminal of the condenser. A varistor(BR1) absorbs shock energy generated for absorbing electromagnetic wave noise by using the coils. A condenser(C6-C7) reduces an amount of electric current by diving a coil(L3-L18) into the high terminal and the low terminal for rectifying the absorbed shock electric current. A coil(L19-L32) is connected to a common terminal for automatically stopping the acting of the motor and a plus terminal in series for removing the electromagnetic wave noise. A condenser(C12-C14) is mounted on the specific portion of the coils for rectifying the electric current.
