1. An optical element driving mechanism comprising:
a fixed portion;
a first movable portion, movable relative to the fixed portion;
a driving assembly, driving the first movable portion to move relative to the fixed portion;
one or more first guiding assemblies, each comprising:
a first guiding element, protruding from an upper surface of the fixed portion; and
a first guiding opening, disposed on the first movable portion, wherein the first guiding element passes through the first guiding opening;
a second movable portion with a plastic material, being parallel to the fixed portion, and movable relative to the first movable portion; and
a second guiding assembly, comprising:
a second guiding element, protruding from a lower surface of the second movable portion;
a second guiding opening, disposed on the first movable portion, wherein the second guiding element passes through the second guiding opening; and
a limiting cavity, disposed on the fixed portion, corresponding to the second guiding element and limiting the moving range of the second guiding element;
wherein the first movable portion leads an optical element to move;
wherein with the one or more first guiding assemblies, the first movable portion is movable relative to the fixed portion in a first dimension; and
wherein with the second guiding assembly, the first movable portion leads the second movable portion to move relative to the fixed portion in a second dimension.
