To provide a lens unit, a camera module, an imaging system, and a mobile body which can efficiently heat a first lens by a heater.SOLUTION: The lens unit includes: a lens group L in which a plurality of lenses are arranged along the optical axis of the lens; a lens-barrel 12 for storing and holding the lens group L; a first lens 13 located closer to an object; a heater 30 for heating the first lens 13; and a heat propagation suppression member 35 for suppressing propagation of heat from the heater in a site other than the first lens. The heater 30 is provided in a seal member 26 formed between the first lens 13 and the lens-barrel 12, and the heat propagation suppression member 35 is formed between the seal member 26 and the lens barrel 12.SELECTED DRAWING: Figure 1
【課題】ヒータによって第1レンズを効率的に加熱することができるレンズユニット、カメラモジュール、撮像システムおよび移動体を提供する。【解決手段】複数のレンズが当該レンズの光軸に沿って並べられたレンズ群Lと、このレンズ群Lを収容保持する鏡筒12と、最も物体側に位置する第1レンズ13と、この第1レンズ13を加熱するヒータ30と、第1レンズ以外の部位に前記ヒータによる熱が伝導するのを抑制する熱伝導抑制部材35を備え、第1レンズ13と鏡筒12との間に設けられたシール部材26の内部にヒータ30が設けられ、シール部材26と鏡筒12との間に熱伝導抑制部材35が設けられている。【選択図】図1
