To provide a lens unit and camera module, capable of obtaining visibility in a short time by directly heating the surface of a lens surface to promptly melting snow, etc, and contributing to downsizing and cost reduction.SOLUTION: A lens unit 11 comprises: a transparent conductive film 31 provided on a lens surface 13a facing the side of an object in a lens 13 constituting a lens group L and positioned closest to the side of the object; at least a pair of electrodes 32A and 32B electrically connected to the transparent conductive film 31; and lens heating means 48 for passing a current through the transparent conductive film 31 by applying a voltage between electrodes 32A and 32B to generate Joule heat in the lens surface 13a.SELECTED DRAWING: Figure 1
【課題】レンズ表面を直接的に暖めて迅速な融雪等を実現することにより短時間で視認性を確保できるとともに小型化および低コスト化にも寄与し得るレンズユニットおよびカメラモジュールを提供する。【解決手段】本発明のレンズユニット11は、レンズ群Lを構成する最も物体側に位置されるレンズ13の物体側に面するレンズ表面13aに設けられる透明導電膜31と、透明導電膜31に電気的に接続される少なくとも一対の電極32A,32Bとを有し、電極32A,32B間に電圧を印加することにより透明導電膜31に電流を流してレンズ表面13aでジュール熱を発生させるレンズ加熱手段48を備える。【選択図】図1
