Abstract: Disclosed is a sensor unit having a simple sensor structure to detect intensity of force applied to a parking cable upon braking a vehicle and an electronic parking brake with the same. The disclosed sensor unit includes a sensor housing, in which a Hall IC is installed to sense variation of magnetic force caused by displacement of a magnet, a magnet housing arranged to be movable within the sensor housing, the magnet being installed in the magnet housing, and an elastic member arranged between the magnet housing and the sensor housing, to elastically support the magnet housing. The magnet housing is coupled to a power conversion unit to operate for pulling of the parking cable or release of the pulling.
