Optical module

An optical module, having a first side and a second side, comprising:

• a movable portion, holding an optical element with an optical axis;
• a fixed portion, comprising a base and a circuit component, wherein the circuit component has an external electrical connection portion and an internal electrical connection portion, and the movable portion is movably connected to the fixed portion;
• a driving portion, configured to drive the movable portion to move relative to the fixed portion;
• a position-sensing portion, comprising a position-sensing element, wherein the position-sensing element is configured to sense a position of the movable portion relative to the fixed portion;
• and
• a circuit board, electrically connected to the position-sensing element, wherein the position-sensing element is disposed on the circuit board,
• wherein the circuit board is disposed on the first side, and the external electrical connection portion is disposed on the second side,
• wherein the second side is perpendicular to the first side,
• wherein the external electrical connection portion has a plurality of terminals, and the terminals are arranged along a direction that is perpendicular to the first side,
• wherein the internal electrical connection portion has a plurality of terminals, and the terminals are arranged along the first side and connected to the circuit board, the circuit board further has a dentate structure to receive the internal electrical connection portion, and the circuit board and the internal electrical connection portion partially overlap when viewed along a direction parallel to the optical axis.
