Title:
MAGNETIC SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/048743
Kind Code:
A1
Abstract:
A magnetic sensor device (1) comprises: a wiring board (2); a plurality of magnetic detection elements (4) mounted on the wiring board (2); and a rectangular integrated circuit (3) electrically connected to the plurality of magnetic detection elements (4). When viewed from the normal direction of the wiring board (2), the plurality of magnetic detection elements (4) are arranged outside the integrated circuit (3), and magnetic detection elements (4) having magnetic sensing directions that are parallel to each other are arranged at least at positions along each of two mutually opposing sides, namely (31a) and (31b), or (31c) and (31d), of the integrated circuit (3).
