A camera module for a mobile device is reduced in size and manufacturing cost. A filter material made of a multi-layer thin film is bonded to a surface of a lens which is bonded to a surface of an image sensor chip. The filter material is a filter to block radiation within a predetermined range of wave length in an incident radiation to the lens, for example, an IR filter to block infrared radiation. An iris material made of a film such as an acrylic film or a polyolefin film is bonded to the lens covered with the filter material.
