Abstract
Provided is a lens barrel with which it is possible to suppress the influence of a disturbance magnetic field on a magnetic sensor. A coil that surrounds an outer periphery of a lens frame, magnetic force applying members that are disposed at a plurality of positions around the lens frame, and a magnetic sensor that detects an amount of movement of the lens frame are provided. In a plane orthogonal to an optical axis, the magnetic force applying members that are disposed on both sides adjacent to the magnetic sensor are disposed in postures in which a first angle (θ) formed between a first straight line (L) and a second straight line (L) is smaller than 45°, the first straight line (L) being a straight line passing through the magnetic sensor and the optical axis and the second straight line (L) being a straight line orthogonal to surfaces of a first yoke and a second yoke of the magnetic force applying member that face each other.
