To provide a lens unit with which it is possible to prevent the breakage of a sealant that seals an extraction hole from the outside.SOLUTION: An airtight closed space S2 is demarcated inside of an inside accommodation space S by an object-side sealant 27 that seals a gas circulation path on the object side that heads toward the inside of an inter-lens space S1 and an image-side sealant 50 that seals the gas circulation path on the image side that heads toward the inside of the inter-lens space S1. In a lens barrel 12 is formed an extraction hole 12b that extends from the closed space S2 to the outside of the lens barrel, and a hole sealant 60 is provided that seals the extraction hole 12 from the outside of the lens barrel 12 while an electric wiring 36 extending from an electronic component 30 disposed inside of the lens barrel 12 is led out of the lens barrel through the extraction hole 12b. The hole sealant 60 is composed of a first sealing layer 62 that holds the sealed state of the extraction hole 12b against a change of pressure in the closed space S2 and a second sealing layer 64 that covers the first sealing layer 62 from the outside for reinforcement.SELECTED DRAWING: Figure 1

    【課題】引き出し孔を外側から封止する封止材の破れを防止し得るレンズユニットを提供する。【解決手段】レンズ間空間S1内へと向かう気体流通経路を物体側で遮断するように封止する物体側封止材27と、レンズ間空間S1内へと向かう気体流通経路を像側で遮断するように封止する像側封止材50とによって、内側収容空間S内に気密な密閉空間S2が画定され、鏡筒12には、密閉空間S2から鏡筒外部へと延びる引き出し孔12bが形成されるとともに、鏡筒12内に設けられる電子部品30から延びる電気配線36が引き出し孔12bを通じて鏡筒外部に導出された状態で引き出し孔12を鏡筒12の外側から封止する孔封止材60が設けられ、孔封止材60は、密閉空間S2内の圧力の変化に抗して引き出し孔12bの封止状態を保持する第1の封止層62と、第1の封止層62を外側から覆って補強する第2の封止層64とによって構成される。【選択図】図1
