Claim 13:
14. A photographing module comprising:
a lens assembly comprising at least one lens element;
a reflection element located on an object side of the lens assembly, wherein the reflection element has a reflection surface, and the reflection surface is configured to redirect an incident light traveling along an incident optical axis towards the lens assembly;
an image sensor disposed on an image surface of the lens assembly, wherein the image sensor is configured to receive light coming from the lens assembly;
a lens element driving module comprising an axial voice coil motor, wherein the lens element driving module drives the lens assembly to move along a lens optical axis of the lens assembly by the axial voice coil motor; and
a reflection element driving module comprising:
a carrier, wherein the reflection element is disposed on the carrier;
a holder disposed corresponding to the carrier, wherein the carrier is movable relative to the holder;
a rotating connection part located between the holder and the carrier, wherein the rotating connection part is disposed on one of the holder and the carrier;
a curved recess structure located between the holder and the carrier, wherein the curved recess structure is disposed on another one of the holder and the carrier, the rotating connection part is in physical contact with the curved recess structure, and the curved recess structure is rotatable relative to the rotating connection part; and
a lateral voice coil motor configured to drive the carrier to rotate around a first axis and rotate around a second axis, wherein the first axis is orthogonal to the incident optical axis, the first axis is orthogonal to the lens optical axis, the second axis is parallel to the incident optical axis, and both of the first axis and the second axis pass through the rotating connection part;

wherein a curvature radius of the curved recess structure is Rc, a curvature radius of the rotating connection part is Rb, and the following condition is satisfied:

0.7≤Rb/Rc≤1.
