A multi-turn absolute torque angle sensor module according to the present invention includes a main gear magnet (10) which includes a first magnet part in which a master track and a nonius track which are formed of straps, in which magnets having different polarities are alternately disposed, are vertically disposed on a circumferential surface portion of the first magnet part and the polarity distributions of the master track and the nonius track are disposed to be shifted from each other by a difference of one or more polarities, wherein a main gear is disposed at an upper side in the main gear magnet and connected to one side of a torque shaft, a pinion gear magnet (20) connected to the main gear and including a second magnet part including a pinion gear of which the number of gears is less than the number of gears of the main gear and a magnet installed on the pinion gear, a circuit substrate (30) disposed under the main gear magnet and the pinion gear magnet, first and second sensor parts disposed on the circuit substrate to detect magnetic forces of the first and second magnet parts, respectively, and a case which is vertically coupled and has an accommodation space accommodating the main gear magnet, the pinion gear magnet, and the circuit substrate and through which the torque shaft passes.
