Claim 13:
14. The lens module according to claim 1, wherein
the first detection-target magnetic field includes a first magnetic field component and a second magnetic field component,
the first magnetic field component is a component of a magnetic field parallel to a first reference plane at a first detection position, and is a component of a composite magnetic field of two magnetic fields that are respectively generated by the second magnet and the third magnet,
the second magnetic field component is a component of the magnetic field parallel to the first reference plane at the first detection position, and is a component of a magnetic field generated by the fifth magnet,
the second detection-target magnetic field includes a third magnetic field component and a fourth magnetic field component,
the third magnetic field component is a component of a magnetic field parallel to a second reference plane at a second detection position, and is a component of a composite magnetic field of two magnetic fields that are respectively generated by the first magnet and the fourth magnet, and
the fourth magnetic field component is a component of the magnetic field parallel to the second reference plane at the second detection position, and is a component of a magnetic field generated by the sixth magnet.
