To provide a torque detection device which allows less deformation of detection coils than in the conventional techniques in axially pressing and holding in yokes, coil bobbins around which the detection coils are wound. A torque sensor (TS) includes a pair of coils (13a, 13b), coil bobbins (18Aa, 18Ab) around which the coils (13a, 13b) are respectively wound, yokes (15a, 15b) which respectively hold the coil bobbins (18Aa, 18Ab), one yoke cover (14) fitted by pressing into inner diameters of the yokes (15a, 15b), and pressing portions (18c) which are formed to project radially and outward at a plurality of circumferential positions of a radial outer end portion of respective flange portions (18b) of the coil bobbins (18Aa, 18Ab), and act between the coil bobbins (18Aa, 18Ab) to axially press the coil bobbins (18Aa, 18Ab) during assembly.
