1. A camera module, the camera module comprising:
a base supporting a filter member mounted on a position corresponding to that of an image sensor mounted on a PCB (Printed Circuit Board); and a dust trap unit mounted about the filter member of the base to collect soils including dust introduced into the filter member, wherein the dust trap unit includes an epoxy reception groove formed with one or more ribs formed at a periphery of the filter member mounted at the base, and a dust trap epoxy coated on an inside of the epoxy reception groove; wherein the epoxy reception groove comprises:
a first rib member protruded from an edge of a window exposing a filter centrally mounted on the base;a second rib member provided across the epoxy reception groove from the first rib member;a third rib member connected at both distal ends to the first and second rib members and arranged to have a first angle relative to the first and second rib members; anda fourth rib member connected at both distal ends to the first and second rib members and arranged to have a second angle relative to the third rib member,whereby strength of the base is reinforced, and wherein the dust trap epoxy is coated on a space unit formed by the connection of the first, second, third, and fourth rib members.
