1. A magnetic sensor device comprising:
a magnetic field converter that receives an input magnetic field including a magnetic field component along a first direction and outputs an output magnetic field including a magnetic field component along a second direction, which is orthogonal to the first direction;
a magnetic field detector provided at a position where the output magnetic field can be applied; and
a magnetic shield that shields external magnetic field components along a third direction, which is orthogonal to both the first direction and the second direction;
wherein the magnetic field converter is made of a soft magnetic material;
when viewed along the first direction, the magnetic field converter has a shape such that a length in the third direction is greater than a length in the second direction;
when viewed along the first direction, the magnetic shield is provided at a position overlapping the magnetic field converter and the magnetic field detector; and
a magnetic field transmittance of the external magnetic field is 1˜30%.
