Turning angle detection device

This resolver-type turning angle detection device (100) comprises: a stator (1) provided with a stator core (11) having a plurality of teeth (11B) protruding towards a diametrical direction (Z) from a ring-shaped core back (11A), a winding (12) wound on the teeth (11B), and an insulator (13) arranged between the stator core (11) and the winding (12); and a rotor (2), and is further provided with a distal end flange (14) of the teeth (11B), a partition plate (15) situated in an intermediate part of the teeth (11B), and a base-side wall (16) of the teeth (11B). A first cutout portion (151) recessed in the axial direction is provided to a first side surface (15A) constituting one of the axial side surfaces of the partition plate (15), and a first lead-in wire (171) and a second lead-out wire (172) of the distal end winding pass through the first cutout portion (151). 旋转变压器方式的旋转角度检测装置(100)由定子(1)和转子(2)构成，该定子(1)具备具有从圆环状的铁芯背(11A)向径向(Z)突出的多个齿(11B)的定子铁芯(11)、卷绕在齿(11B)上的绕组(12)、以及配置在定子铁芯(11)与绕组(12)之间的绝缘体(13)，该旋转角度检测装置(10
