A magnetic sensor of a sensor unit includes magnetic sensing elements, an encapsulating portion, a primary terminal group and a secondary terminal group. Another magnetic sensor includes magnetic sensing elements, an encapsulating portion, a primary terminal group and a secondary terminal group. The magnetic sensors are mounted on a common surface of a circuit board. The adjacent two magnetic sensors, which are oriented in a common direction, are arranged such that the secondary terminal group of one of the adjacent two magnetic sensors is opposed to the primary terminal group of the other one of the adjacent two magnetic sensors. A primary output terminal and a secondary output terminal are placed asymmetrically to each other with respect to a center line of the encapsulating portion. |

1. A sensor unit comprising:
a plurality of magnetic sensors, each of which includes:
a magnetic sensing element, which senses a magnetic field;an encapsulating portion, which encapsulates the magnetic sensing element;a primary terminal group, which includes a plurality of terminals that project from a primary terminal forming part of the encapsulating portion, wherein the primary terminal forming part is one side of the encapsulating portion; anda secondary terminal group, which includes a plurality of terminals that project from a secondary terminal forming part of the encapsulating portion, wherein the secondary terminal forming part is an opposite side of the encapsulating portion, which is opposite from the primary terminal forming part of the encapsulating portion; and a circuit board that has a common surface, to which the plurality of magnetic sensors is mounted, wherein: adjacent two of the plurality of magnetic sensors, which are oriented in a common direction and are arranged side by side, are arranged such that the secondary terminal group of one of the adjacent two of the plurality of magnetic sensors is opposed to the primary terminal group of the other one of the adjacent two of the plurality of magnetic sensors; the plurality of terminals of the primary terminal group of each of the plurality of magnetic sensors includes a primary output terminal for outputting an output signal generated based on a measurement value of the magnetic sensing element of the magnetic sensor; the plurality of terminals of the secondary terminal group of each of the plurality of magnetic sensors includes a secondary output terminal for outputting the output signal; and the primary output terminal and the secondary output terminal are placed asymmetrically to each other with respect to a center line centered between the primary terminal forming part and the secondary terminal forming part in each of the plurality of magnetic sensors. |
