Lens unit and camera module

摘要

PROBLEM TO BE SOLVED: To provide a lens unit and a camera module for preventing an antireflection film on a lens surface from being adversely affected by heat of a heater for warming a lens. SOLUTION: A lens unit 11 of the present invention has an antireflection film on the surface of a resin second lens 14 adjacent to a glass first lens 13 located on the most object side forming a lens group L. 30A is provided, and the heater 40 is inserted between the surface 13b of the first lens 13 facing the image side and the surface 14a of the second lens 14 facing the object side. The antireflection film 30A has heat resistance in which the film formation state does not change in appearance due to thermal expansion of the second lens 14 due to the heat of the heater 40.
