徴とするトルク検出装置。 An excitation coil is attached to a set of diagonal legs of a table-shaped ferrite magnetic core, each of which has columnar legs erected at the four corners of a substantially rectangular main surface of a flat plate such as a square plate or a circular plate. Detection coils are attached to the other pair of legs to serve as excitation poles and detection poles, and the tips of each magnetic leg are placed opposite to the outer peripheral surface of a power transmission rotating shaft made of a magnetic material with a gap therebetween. In a torque detection device that detects torque applied to the rotating shaft, a set of magnetic legs is positioned in a plane perpendicular to the central axis of the rotating shaft, and an extension line thereof is oriented in the direction of the central axis of the rotating shaft. The coil attached to each magnetic leg is made of a multilayer printed coil made by laminating a plurality of flexible substrates on which printed coils are formed, and the flexible laminated substrate is tilted to the surface of the flat plate of the core. A torque detecting device, characterized in that the magnetic leg is fixed so as to be substantially flush with the tip of the magnetic leg.
