Lens module and electronic device including gas escape structure

An electronic device comprising a lens module, the lens module comprising:

• a circuit board;
• a carrier fixed on the circuit board and defining a surface away from the circuit board, the surface of the carrier defining a through hole, a groove adjacent to the through hole, and a gas escape structure;
• an optical filter;
• and
• a lens holder mounted on the surface of the carrier;
• wherein the optical filter is fixed in the groove through an adhesive layer, the optical filter and the circuit board close opposite ends of the through hole to form a receiving space, the gas escape structure communicates with the receiving space to allow the release of water vapor generated in the receiving space;
• the gas escape structure comprises a first gas escape structure portion and a second gas escape structure portion, the first gas escape structure portion is defined on a sidewall of the groove and defines an opening on the surface of the carrier, the second escape structure portion is defined at a bottom of the groove and communicates with the first escape structure portion, the lens holder closes the opening.
