An actuator for an electromechanical parking brake having a housing with a brush card assembly of the present invention includes: a main housing (10) having a motor seat (11) and a gear seat (21); a motor assembly (23) disposed in the motor seat (11) and providing torque; a gear assembly (50) rotated by torque from the motor assembly and performing a reduction function through a plurality of gears (51, 52, 70); and an inner housing (30). The inner housing (30) is combined with the main housing (10) and fixes the gear assembly (50). A ring gear (37) operating with a planetary gear set (70) and a brush card (34) electrically connected to the motor assembly are integrally formed at the inner housing (30) of the present invention.
