Optical element driving mechanism

An optical element driving mechanism, comprising:

• a bottom,
• a movable part connected to an optical element with an optical axis, wherein the movable part is movable relative to the bottom;
• a driving assembly driving the movable part to move relative to the bottom;
• a first circuit assembly disposed on the bottom and electrically connected to the driving assembly;
• and
• a second circuit assembly electrically connected to the driving assembly, wherein at least part of the second circuit assembly is embedded in and not revealed from the bottom;
• wherein the driving assembly is electrically connected to the first circuit assembly via the second circuit assembly;
• wherein the second circuit assembly comprises a first electrical connection portion and a second electrical connection portion that are located at different heights.
