Description

本発明の撮像ユニットは、撮像手段と、前記撮像手段よりも被写体側に配置される光学部材と、前記撮像手段を撮影者側で保持すると共に、前記光学部材を被写体側で保持する保持部材と、前記保持部材の撮影者側に設けられ、前記撮像手段を前記保持部材に固定した際に、前記撮像手段と前記保持部材の間を封止して密閉空間を形成する第一の封止部材と、前記保持部材の被写体側に設けられ、前記光学部材を前記保持部材に固定した際に、これら光学部材と保持部材の間を封止して密閉空間を形成する第二の封止部材とを備え、前記第一の封止部材と前記第二の封止部材は分離して形成され、前記第二の封止部材の底面は、前記第一の封止部材の底面よりも前記撮像手段側へ突出していることを特徴とする。 Image pickup unit of the present invention includes an imaging unit, and an optical member disposed on the object side of the imaging means, and holds the image pickup means photographer side, a holding member for holding the optical member at the object side , provided to the photographer side of the holding member, said imaging means when fixed to the holding member, the first seal that form a closed space sealed between the holding member and the imaging device and the member, provided on the object side of the holding member, the optical member when fixed to the holding member, the second sealing that form a sealed and closed space between these optical members and the holding member A first sealing member and the second sealing member are formed separately, and the bottom surface of the second sealing member is more than the bottom surface of the first sealing member. It characterized that you have projected to the imaging device side.
