Abstract: A camera module comprising: a lens barrel comprising a lens; a lens holder for accommodating the lens barrel; an image sensor disposed below the lens barrel; a printed circuit board on which the image sensor is mounted and is coupled to the lens barrel; and at least one welding point for mutually coupling the lens barrel and the lens holder while an optical axis of the lens and an optical axis of the image sensor are aligned.

Abstract: A lens array of an embodiment comprises: a plurality of lenses arranged along an optical axis direction between an object and an image forming plane; a first spacer placed among the plurality of lenses; and an elastic member placed between the lower surface of the first spacer and an upper surface of at least one lens between first and second lenses, which have different widths, face the lower surface of the first spacer, and are arranged side by side along the optical axis direction among the plurality of lenses.

Abstract: 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.
