Abstract
A magnetic sensor device includes a sensor substrate and a sensor element circuitry. The sensor substrate has a surface. The sensor element circuitry is provided on the surface of the sensor substrate and includes one or more magnetic sensor elements. As viewed in a plane parallel to the surface, the sensor substrate has a perimeter that is substantially octagonal. The perimeter includes two short sides opposed to each other, two long sides opposed to each other, and four corners. The four corners are each chamfered entirely or partially in a thickness direction that is substantially orthogonal to the surface. A ratio of a length of each of the four corners along each of the two long sides of the sensor substrate to a length of each of the two long sides of the sensor substrate is less than or equal to 0.39.
