SENSOR CHIP, DETECTING DEVICE, AND METHOD FOR MANUFACTURING DETECTING DEVICE

摘要

[Object] To provide a highly reliable detection device for accurately detecting the azimuth while reducing the size of the detection device. [Means for Solving the Problem] The detection device includes an X-axis magnetic sensor 7a, a Y-axis magnetic sensor 7b, and a Z-axis magnetic sensor 7c each having a sensing axis 8 for detecting a geomagnetic azimuth and a sensor controlling semiconductor 9. The magnetic sensors 7 are selected from those fabricated from the same wafer, each having the same structure, and directly mounted on the circuit substrate 3 by directing the respective sensing axes 8 of the magnetic sensors 7 at different predetermined angles. Electrodes 15a, 15b and 15c of the magnetic sensors 7 for conducting the sensor controlling semiconductor 9 are located in a parallel row at one side of the sensing surface.
