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

摘要

[PROBLEMS] To provide a detecting device which detects accurate direction and has high reliability and to reduce sizes of the detecting device. [MEANS FOR SOLVING PROBLEMS] A detecting device is provided with an X-axis magnetic sensor (7a) having a sensitivity shaft (8) for detecting the direction of earth magnetism, a Y-axis magnetic sensor (7b), a Z-axis magnetic sensor (7c) and a sensor control semiconductor (9). Each magnetic sensor (7) is selected from the magnetic sensors which are manufactured on the same wafer and have the same configuration, and the sensitivity shafts (8) of the magnetic sensor (7) are directly arranged on a circuit board (3) at prescribed angles different from each other, and electrodes (15a, 15b, 15c) for carrying electricity between a sensor controlling semiconductor (9) of each magnetic sensor (7) are arranged in parallel in a row on one side of a sensitivity surface.
