Abstract
An electromagnetic driving mechanism is provided, including a housing, a circuit unit, an electromagnetic driving assembly, and a sensing element. The circuit unit is connected to the housing, and has a plastic material and a circuit element. The plastic material is formed on and covers an outer surface of the circuit element by insert molding. The electromagnetic driving assembly is disposed in the housing for forcing an optical element to move relative to the circuit unit. The sensing element is disposed on the circuit unit, and electrically connected to the circuit element for detecting the displacement of the optical element relative to the circuit unit.
