Abstract

To provide a lens unit and a camera module which can stably and reliably heat a first lens positioned closest to an object by a planar heater.SOLUTION: A lens unit includes: a plurality of lenses arrayed along an optical axis; a lens barrel 12 for storing and holding the plurality of lenses; and a planar heater 50 capable of heating a first lens 13 positioned closest to an object. The planar heater 50 includes a heating part 51 for heating the first lens 13. The heating part 51 is bonded to an end surface 13a on the image side of the first lens 13 by an adhesive so that the first lens 13 can be stably and reliably heated by the planar heater 50.SELECTED DRAWING: Figure 1
