A nonadjustable focusing type camera module includes a lens assembly having at least one lens, a lens accommodating part mounted on an upper surface of a substrate, and a barrel having an inner space in which the lens assembly is arranged along an optical axis. An upper cap having an incident hole formed in a front center thereof is fixed to the upper side of the barrel to apply pressure to the lens assembly along the optical axis. The camera module further includes an image sensor having an image forming plane on which a light passed through the lens is focused. The sensor is electrically connected to the substrate to transmit the focused image, and a filter is disposed between the lens assembly and the image sensor.
