A camera module, comprising:
- a liquid lens comprising:
- a first plate having a first surface and a second surface opposite the first surface, the first surface having a larger area than the second surface;
- a second plate disposed on the first surface;
- a conductive liquid;
- an insulative liquid;
- an individual electrode disposed on the first surface of the first plate;
- and
- a common electrode disposed on the second surface of the first plate, the common electrode being in direct contact with the conductive liquid;
- a temperature detection element disposed on the first surface of the first plate so as to be spaced apart from the individual electrode;
- a heating element disposed on the first surface so as to be spaced apart from the temperature detection element and the individual electrode;
- a temperature sensor connected to the temperature detection element to sense a temperature of the liquid lens;
- a heating controller connected to the heating element, wherein the individual electrode is located closer to an outer edge of the first surface than the temperature detection element and the heating element;
- and
- a connection substrate connected to the individual electrode and the temperature detection element,
- wherein the second plate includes a plurality of recesses exposing a first end of the temperature detection element and a second end of the heating element, and
- wherein the connection substrate includes a plurality of protruding portions protruding toward the plurality of recesses to be connected to the first and second ends.
