1. An optical element driving mechanism, comprising:
a fixed part having a main axis, the fixed part comprising:
a case made of non-metal material; and
a bottom, wherein the case and the bottom are arranged along the main axis;
a movable part moving relative to the fixed part; and
a driving assembly driving the movable part to move relative to the fixed part;
an elastic element, wherein the movable part is movably connected to the bottom via the elastic element;
a loop member comprising a first electrical connection portion;
an outside-connection circuit member allowing current to flow in or flow out the optical element driving mechanism and parallel with the main axis; and
an electronic element disposed on the bottom and close to the outside-connection circuit member,
wherein the bottom comprises a supporting platform, and the first electrical connection portion is revealed from the supporting platform,
wherein the elastic element comprises a connection portion, the connection portion is disposed on the supporting platform, and the connection portion is in contact with the first electrical connection portion,
wherein the bottom comprises two baffles protruding from one side of a bottom surface of the bottom, the two baffles are in direct contact with the outside-connection circuit member, and the electronic element is located between the two baffles.
 
11. An optical element driving mechanism, comprising:
a fixed part having a main axis, the fixed part comprising:
a case made of non-metal material; and
a bottom, wherein the case and the bottom are arranged along the main axis;
a movable part moving relative to the fixed part; and
a driving assembly driving the movable part to move relative to the fixed part;
an elastic element, wherein the movable part is movably connected to the bottom via the elastic element;
a circuit assembly;
an outside-connection circuit member allowing current to flow in or flow out the optical element driving mechanism and connected to the circuit assembly;
a loop member comprising a first electrical connection portion; and
an electrical connection piece,
wherein the bottom comprises a supporting platform, and the first electrical connection portion is revealed from the supporting platform,
wherein the elastic element comprises a connection portion, the connection portion is disposed on the supporting platform, and the connection portion is in contact with the first electrical connection portion,
wherein a portion of the loop member is embedded in the bottom, the loop member comprises a projecting portion sticking out and corresponding to the elastic element and the circuit assembly, and the electrical connection piece is in direct contact with the elastic element, the circuit assembly, and the loop member, so the circuit assembly is electrically connected to the loop member via the electrical connection piece.
