An embodiment provides a magnetic sensor capable of improving resistance to a strong magnetic field resistance. A magnetic sensor according to an embodiment includes a plurality of element portions 9, bias layers 10 which are provided on both sides of each element portion, and soft magnetic bodies 12 which are provided so as not to contact each element portion and each bias layer. The sensitivity axis direction P1 of the element portion 9 and the magnetization direction of the bias layer 10 are the Y1-Y2 direction. Each bias layer 10 is configured such that a bias magnetic field is supplied to the element portion 9 in the X1-X2 direction. When the external magnetic field is applied in the X1-X2 direction, each soft magnetic body is configured such that it can convert the magnetic field substantially in the Y1-Y2 direction and supply the magnetic field to the element portion 9. A gap T1 is provided between the element portion 9 and the soft magnetic body 12 in a plan view. The bias layer 10 does not overlap a virtual line E which connects edge portions 12d where the distance between the soft magnetic bodies 12 is the shortest in a straight line in a plan view. In addition, the bias layer 10 is not provided between the soft magnetic bodies 12 in an element-connected body 17. |
