1. An optical element driving mechanism, comprising:
a fixed portion;
a first movable portion used for moving relative to the fixed portion and including a first plane, a second plane, and a third plane;
a second movable portion used for holding an optical element having a main axis, and is movable relative to the first movable portion;
a first driving assembly used for driving the first movable portion to move relative to the fixed portion in a first dimension; and
a second driving assembly used for driving the second movable portion to move relative to the fixed portion in a second dimension, wherein the first dimension and the second dimension are different;
wherein:
the first plane, the second plane, and the third plane face the second movable portion;
the first plane and the second plane are perpendicular;
the first plane and the third plane are perpendicular;
the second plane and the third plane are parallel;
a first recess is formed on the first plane;
a second recess is formed on the second plane;
a third recess is formed on the third plane;
the first recess has an arc-shape with a second axis as a central axis;
the second recess has an arc-shape with the second axis as a central axis;
the third recess has an arc-shape with the second axis as a central axis.
