The present invention provides a fixed-focus camera module and a manufacturing method therefor. The fixed-focus camera module comprises a light-sensitive chip, an optical lens assembly, and a lens base. The optical lens assembly is directed packaged in the lens base, and the optical lens assembly is kept in a light-sensitive path of the light-sensitive chip. In this manner, the size and the manufacturing costs of the fixed-focus camera module can be effectively reduced, so as to improve the product competitiveness of the fixed-focus camera module.
