Provided is an endoscope imaging apparatus that can be reduced in size in the direction along the optical axis of an objective optical system and contribute to downsizing of an imaging unit of an endoscope. An imaging device 60 disposed at the distal end portion 17 of the endoscope includes a lens barrel 62 that holds an objective optical system 62a that captures and forms image light of an observation site, and an optical path of image light that has passed through the objective optical system 62a. A right angle prism 64 that bends the direction of the right angle, an image pickup element 70 in which an image pickup surface 70a is disposed along a plane orthogonal to the direction of the optical path bent by the right angle prism 64, and a substrate on which the image pickup element 70 is mounted. 68. The substrate 68 has a distal end side region extending toward the distal end side relative to the imaging element mounting region on which the imaging element 70 is mounted, and electronic components of the drive circuit 76 necessary for driving the imaging element 70 are provided in the distal end side region. Implemented.対物光学系の光軸に沿った方向の大きさに関して小型化を図り、内視鏡の撮像部の小型化に寄与することができる内視鏡用撮像装置を提供する。内視鏡の先端部１７に配置される撮像装置６０は、被観察部位の像光を取り込み結像する対物光学系６２ａを保持する鏡筒６２と、対物光学系６２ａを通過した像光の光路の方向を直角に曲げる直角プリズム６４と、直角プリズム６４により曲げられた光路の方向に対して直交する面に沿って撮像面７０ａが配置された撮像素子７０と、撮像素子７０が実装される基板６８とを有する。基板６８は、撮像素子７０が実装される撮像素子実装領域よりも先端側に延在する先端側領域を有し、その先端側領域に撮像素子７０の駆動に必要な駆動回路７６の電子部品が実装される。
