A camera module comprising:

• a housing that is formed in a rectangular box shape and has a cylindrical barrel coupling portion extending upward from a central portion thereof;
• an image sensor module that is mounted in the housing;
• a lens barrel that includes:
• a lens insertion port provided in a central portion of the lens barrel;
• and
• a housing coupling portion extending downward from the lens barrel, the housing coupling portion being closely coupled to the barrel coupling portion of the housing;
• a wafer lens that is mounted in the lens insertion port of the lens barrel;
• and
• a lens fixing cap that is covered on the upper end portion of the lens barrel,
• wherein a male screw portion is formed on an outer circumference of the cylindrical barrel coupling portion and a female screw portion is formed on an inner circumference of the housing coupling portion, and
• wherein the housing and the lens barrel are coupled to each other by screw-coupling between the male screw portion and the female screw portion.
