Patent ID: 10788544

Abstract:
A magnetic sensor includes a sensor chip 30 including an element-forming surface 31 provided with a magnetism detection elements MR1-MR4, a magnetic member 40 including a first side surface 41 facing the element-forming surface 31, and a circuit board 20 including a mounting surface 21 on which the sensor chip 30 and the magnetic member 40 are mounted. The sensor chip 30 and the magnetic member 40 are mounted on the circuit board such that the element-forming surface 31 and the first side surface 41 are substantially orthogonal to the mounting surface 21 of the circuit board 20. Because the sensor chip 30 and the magnetic member 40 are mounted on the circuit board 20 in a horizontal state, the magnetic member 40 can be supported in a stable manner even when the length of the magnetic member 40 is large.
