1. A magnetic sensor device comprising:
a first chip including a first magnetic sensor,
a second chip including a second magnetic sensor and a third magnetic sensor, and
a support having a reference plane, wherein
the first magnetic sensor includes at least one first magnetic detection element and detects a first component of an external magnetic field, and the first component is a component of the external magnetic field in a first direction,
the second magnetic sensor includes at least one second magnetic detection element and detects a second component of the external magnetic field, and the second component is a component of the external magnetic field in a second direction,
the third magnetic sensor includes at least one third magnetic detection element and detects a third component of the external magnetic field, and the third component is a component of the external magnetic field in a third direction,
the first direction, the second direction, and the third direction are mutually different directions,
the first chip and the second chip are mounted on the reference plane, and
each of the first chip and the second chip has a shape that is longer in a direction orthogonal to a direction of alignment of the first chip and the second chip, when viewed from the direction perpendicular to the reference plane.
