Optical element driving mechanism

An optical element driving mechanism, comprising:

• a fixed part, comprising a base, wherein the base corresponds to an optical module;
• a movable part, connected to an optical element, wherein the movable part is movable relative to the fixed part;
• and
• a driving assembly, driving the movable part to move relative to the fixed part,
• wherein the base comprises an accommodation portion, and the accommodation portion has a recessed structure for accommodating the optical module,
• wherein the base comprises a base first portion and a base second portion,
• wherein in a first direction that is parallel to an optical axis, the base first portion and the accommodation portion at least partially overlap each other,
• wherein in the first direction, the base second portion does not overlap the accommodation portion,
• wherein the accommodation portion corresponds to the optical module,
• wherein the optical element driving mechanism further comprising a connecting element,
• wherein the fixed part further comprises an outer frame,
• wherein the base first portion comprises a base first portion connecting wall, and the base second portion comprises a base second portion connecting wall,
• wherein the connecting element is disposed between the outer frame and the base first portion connecting wall, and between the outer frame and the base second portion connecting wall,
• wherein an area of the base first portion connecting wall is larger than an area of the base second portion connecting wall, and
• wherein the connecting element is glue.
