Lens drive apparatus, camera module and camera

A lens drive apparatus for use in a camera module, which displaces a lens holder in a direction of an optical axis and first and second directions orthogonal to the optical axis and to each other, the lens drive apparatus comprising:

• a drive section that rocks an assembly, which is formed by assembling the lens holder together with a magnet disposed around the lens holder and together with a guide member configured to guide the lens holder such that the lens holder can move with respect to the magnet in the direction of the optical axis, in the first and second directions by the magnet and a first coil disposed at a position facing a first surface of the magnet in collaboration with each other;
• a base that is disposed so as to be spaced from the assembly and has an aperture through which the optical axis passes in a displacement range of the optical axis resulting from rocking of the assembly in the first and second directions;
• a rocking support member configured to support the assembly such that the assembly can rock with respect to the base in the first and second directions;
• and
• a Hall device that detects a position of the magnet in the first and second directions, wherein:
• the lens holder comprises a second coil, disposed at a position facing a second surface of the magnet, configured to move the lens holder with respect to the magnet in the direction of the optical axis in collaboration with the magnet,
• the magnet, the first coil and the Hall device are disposed at positions shifted in the direction of the optical axis, and
• the first coil and the second coil are respectively disposed such that a direction of the first surface of the magnet facing the first coil and a direction of the second surface of the magnet facing the second coil are different from each other.
