Abstract
An optical element driving module is provided, including a housing, a movable portion configured to support an optical element, a driving assembly, a positioning sensor, and a non-metallic substrate disposed on a side of the movable portion. The movable portion is movable relative to the housing, the driving assembly is configured to drive movement of the movable portion relative to the housing, and the positioning sensor is configured to detect the movement of the movable portion relative to the housing. Specifically, the non-metallic substrate forms a recess for receiving the positioning sensor, wherein a depth of the recess is greater than a height of the positioning sensor.
