An electric parking brake system in which an actuator case (39) of an electric actuator (36) configured to drive a parking brake lever (34) to thereby obtain a parking brake state is mounted to a back plate (13) of a drum brake (11) including the parking brake lever (34). A cylinder part (46) configuring a part of the actuator case (39) is inserted in a mounting cylinder part (77) provided to the back plate (13) and is engaged to the mounting cylinder part (77) with axial movement thereof being restrained. One of the mounting cylinder part (77) and the actuator case (39) is formed with an engagement concave part (81) arranged around a central axis of the mounting cylinder part (77), and the other of the mounting cylinder part (77) and the actuator case (39) is formed with an engagement part (45b) engaged with the engagement concave part (81).
