An object of the present invention is to provide a cap having a simple structure for preventing fogging of an optical component provided at a front end of an imaging device and covering a part of the imaging device, and an imaging device. An imaging apparatus for imaging an object includes an optical component, a cylindrical portion for capturing light from the object, a housing including an electronic component for processing the light captured from the cylindrical portion, at least； A cap 10 that covers a part of the cylindrical portion 20 and a blower 37 that is provided in the housing 30 and supplies air to at least one of the optical components provided in the cap 10 and the cylindrical portion 20 are provided. The cap 10 and the portion of the cylindrical portion 20 covered by the cap 10 constitute a ventilation path through which the air supplied from the ventilation section 37 passes. [Selection diagram] Fig. 1【課題】撮像装置の先端に設けた光学部品の曇りを防止すると共に、撮像装置の一部を覆う構造が簡単なキャップ、および撮像装置を提供する。【解決手段】対象物を撮像する撮像装置は、光学部品を含み、対象物からの光を取り込む筒部２０と、筒部２０から取り込んだ光を処理する電子部品を含む筐体３０と、少なくとも筒部２０の一部を覆うキャップ１０と、筐体３０に設けられ、キャップ１０および筒部２０に設けた光学部品のうち少なくとも一方に空気を供給する送風部３７とを備えている。キャップ１０とキャップ１０に覆われた筒部２０の部分とで、送風部３７から供給された空気を通す送風路を構成する。【選択図】図１
