Abstract: The camera module disclosed in the embodiment of the invention includes a lens barrel having a through hole therein; and a lens part disposed in the through hole of the lens barrel and having first to third lenses in which optical axis are aligned from the object side toward the sensor side, and an image sensor. The materials of the second lens and the first lens are different, the refractive index of the second lens is lower than that of the first lens. Each of the first to third lenses includes first to third flange portions extending from the optical axis toward the inner surface of the lens barrel, an outer diameter of the lens barrel at a position where an upper portion of the first flange and the lens barrel are in contact is a first outer diameter, an outer diameter of the lens barrel at a position where an upper portion of the second flange portion and the lens barrel are in contact is a second outer diameter, an outer diameter of the lens barrel at a position where an upper portion of the third flange and the lens barrel are in contact is a third outer diameter, an outer diameter of the lens barrel at a position where an upper portion of the image sensor and the lens barrel are in contact is a four outer diameter, and the third outer diameter is smaller than the fourth outer diameter and greater than the second outer diameter.
