Camera module
The present invention relates to a camera module, and the present invention comprises: a lens unit; a lens barrel for fixing the lens unit; a substrate unit, which has an image sensor mounted thereon, for converting light incident through the lens unit into an electric signal; and a housing accommodating the substrate unit in an inner space thereof and of which one side is coupled to the lens barrel, and the present invention can comprise: a transmission coil accommodated inside the housing so as to form an electric field, and a conductive heating element arranged on an outer surface of the lens unit or on an outer circumferential surface of the lens barrel, and in which an induced current is generated by the electric field formed by the transmission coil. Since the present invention heats a lens by wirelessly supplying power to a heating element through simple configurations such as a transmission coil and the heating element, large changes are unnecessary in the volume and the structure of a camera module. In addition, since the heating element of the present invention does not restrict incident light, an image of a subject is not distorted and a clean image can be obtained, and thus the present invention is efficient. In addition, the present invention prevents signal interference with other electronic components or electrical components when power is wirelessly supplied to a heating element, and thus, camera malfunction can be prevented.
