Problems solved by technology

The injected molten resin comes into contact with the Hall IC in the molding space, and the resin is at a high temperature of, for example, 270°C, so the detection accuracy of the Hall IC may decrease due to the heat generated during molding

Abstract

The present invention provides a detection device and a method of manufacturing the detection device capable of suppressing a decrease in detection accuracy of a sensor due to heat generated when the sensor is molded with resin. The sensor module (3) has: a magnetic field sensor (4), which has a sensor main body (40) including a magnetic field detection element (40a), and a plurality of wires (41) pulled out from the sensor main body (40); A body (31), which has a housing portion (31A) for housing the sensor main body (40); At least a portion of the molded resin is formed.

Description

technical field [0001] The present invention relates to a detection device having a sensor for detecting state quantities such as a magnetic field and temperature, and a method for manufacturing the detection device. Background technique [0002] Conventionally, there is known a torque detection device that molds, for example, a Hall IC as a sensor for detecting a magnetic field with a resin, and detects a force applied to a vehicle based on a change in the intensity of a magnetic field detected by the Hall IC. The torque of the steering wheel (for example, refer to Patent Document 1). [0003] The torque detection device described in Patent Document 1 includes: an input shaft connected to a steering wheel, an output shaft connected to a steering wheel, a torsion bar connecting the input shaft and the output shaft, a multi-pole magnet, a pair of multi-pole yokes, two Hall The Seoul IC uses the torque applied to the steering wheel to twist the torsion bar to make a multi-pol...
