Optical element driving mechanism

An optical element driving mechanism comprising:

• a fixed part comprising a bottom;
• a movable part movable relative to the fixed part and holding an optical element with an optical axis;
• and
• a driving assembly driving the movable part to move relative to the fixed part,
• wherein the bottom comprises:
• a base;
• and
• an embedded assembly partially embedded in the base, wherein the embedded assembly comprises a magnetic-permeable material and a strengthening frame, and the strengthening frame comprises a perforation through which the optical axis passes and a bending portion extending in the optical axis, and
• wherein the base comprises a pillar, and the bending portion is embedded in the pillar.
