A camera module that can obtain a clear image even in the case where dust is generated inside the camera module due to a shock applied thereto is provided. The camera module includes a base and a cover attached to the base so as to define a space therebetween in which the holder can be displaced. The base has an upper surface which faces the cover, and the upper surface of the base includes a concaved dust collecting portion and a dust falling preventing wall formed on the upper surface so as to surround an entire circumference of an opening of the base, and wherein a surface of the concaved dust collecting portion includes a dust sticking layer to which fallen dust is adapted to stick, whereby when dust is generated in the space between the cover and the base and such dust is fallen onto the upper surface of the base, it is possible to prevent such dust from entering into the opening by the dust falling preventing wall and such dust is stuck to the dust sticking layer of the dust collecting portion provided on the upper surface of the base.
