PURPOSE: An apparatus for eliminating electromagnetic wave noise from a wiper motor for a vehicle is provided to reduce a manufacturing cost and a volume by greatly reducing the number of configured elements comparing to an existing structure. CONSTITUTION: A first filter section is connected to an automatic stop positioning device of a wiper motor. The first filter section includes a choke coil(L1) and a Mylar condenser(C1) to eliminate an electromagnetic noise generated due to the on/off operation of the automatic stop positioning device. A second filter section is connected to the wiper motor. The second filter section includes Mylar capacitors(C4,C5) and feed through condensers(C6,C7) to eliminate the electromagnetic noise caused by the rubbing of a permanent magnet and a brush inside the wiper motor. A third filter section is connected to an output terminal of the second filter section. The third filter section includes a core(L2) and Mylar condensers(C8,C9) to eliminate the electromagnetic noise.
