Abstract: In a method for manufacturing a current sensor, a wiring board is placed by bringing the wiring board into contact with board contact portions of a sensor housing while deforming an adhesive applied on top surfaces of board adhesion portions of the sensor housing between the board adhesion portions and the wiring board, and a shield is placed by bringing the shield into contact with shield contact portions of the sensor housing while deforming an adhesive applied on top surfaces of shield adhesion portions of the sensor housing between the shield adhesion portions and the shield. After the placing of the wiring board and the placing of the shield, both the adhesive positioned between the board adhesion portions and the wiring board and the adhesive positioned between the shield adhesion portions and the shield are cured simultaneously.

Abstract: A position detection device includes a substrate disposed to face a displaceable detection object, a transmitting coil provided in the substrate, a first receiving coil and a second receiving coil which are disposed inside the transmitting coil in a normal direction with respect to a surface direction of the substrate, and a signal processing unit that derives a displacement amount of the detection object in view of a gap between the detection object and the substrate, based on a first characteristic value of the first receiving coil and a second characteristic value of the second receiving coil.

Abstract: A torque detection device includes a first yoke and a first magnetic guide member. A first opposing portion of the first magnetic guide member overlaps with a first-yoke ring of the first yoke when the first-yoke ring is projected onto the first opposing portion in an axial direction. Furthermore, the first opposing portion overlaps with an inner surface of a second tubular portion when the inner surface is projected onto the first opposing portion in the axial direction. A housing distance, which is a shortest distance measured from the first opposing portion to the inner surface, is longer than a yoke distance, which is a shortest distance measured from the first opposing portion to the first-yoke ring.
