Camera module and optical device

A camera module comprising:

• a housing;
• a lens module disposed in the housing;
• a substrate disposed below the lens module;
• an image sensor disposed between the lens module and the substrate;
• an optical element unit disposed between the lens module and the image sensor, the optical element unit having an optical surface disposed at the top thereof, to which the light transmitted through the lens module is incident, comes in contact with a light receiving surface of the image sensor at the bottom thereof, and contains a material having a higher refractive index than that of air;
• and
• a package located between the image sensor and the substrate, the package including:
• a base on which the image sensor is mounted;
• and
• a sidewall portion protruding upward from the base such that the image sensor is disposed inside the sidewall portion.

An optical device comprising:

• a body;
• a display unit disposed on one side of the body;
• and
• a camera module electrically connected to the display unit,
• wherein the camera module comprises:
• a housing;
• a lens module disposed inside the housing;
• a substrate disposed below the lens module;
• an image sensor disposed between the lens module and the substrate;
• and
• an optical element unit disposed between the lens module and the image sensor,
• wherein the optical element unit has an optical surface disposed at the top thereof, to which the light transmitted through the lens module is incident, comes in contact with a light receiving surface of the image sensor at the bottom thereof, and contains a material having a higher refractive index than air,
• wherein the optical element unit includes an optical lens unit having the optical surface, and
• wherein an adhesive layer is disposed between the optical lens unit and the image sensor, the adhesive layer being in contact with the light receiving surface of the image sensor at the bottom thereof.
