A lens driving device includes: a lens frame; a supporting unit that supports the lens frame in driving directions; a driving unit that drives the lens frame in one or both of a direction of an optical axis and a direction intersecting the optical axis; and a sensor that is mounted on the supporting unit and detects a position of the lens frame. The supporting unit includes: a circuit that is connectable to the sensor and integral with the supporting unit; and a recess that receives the sensor. The circuit has terminals exposed to a space inside the recess.
