PROBLEM TO BE SOLVED: To provide an intermediate cylinder with an image pickup device excellent in operability.SOLUTION: An intermediate cylinder with an image pickup device comprises an image pickup device 11, a release operation member 15 provided on a top face on an outer peripheral surface, a mount part 12 and a lens attachment/detachment mechanism enabling a replaceable lens barrel 7 to be attached to/detached from a front face, an operation member 14 for detaching a lens cancelling a lens lock state of the lens attachment/detachment mechanism, an installation part 19 and an adaptor attachment/detachment mechanism enabling an adaptor 4 for attaching equipment interposed for connecting other external equipment 3 to the back face side to be attached/detached, and an operation member 18 for detaching an adaptor cancelling an adaptor lock state of the adaptor attachment/detachment mechanism. The intermediate cylinder with an image pickup device is configured such that the operation member for detaching a lens and the operation member for detaching an adaptor are adjacently placed, operation directions of the operation member for detaching a lens and the operation member for detaching an adaptor become the same with each other, and the operation member for detaching a lens and the operation member for detaching an adaptor are placed at positions apart from an installation position of the release operation member only by 90 degrees along an outer periphery in the radial direction.SELECTED DRAWING: Figure 3 【課題】操作性に優れた撮像素子付中間筒を提供する。【解決手段】撮像素子１１と、外周面上における上面に配設されるレリーズ操作部材１５と、交換用レンズ鏡筒７を前面に着脱可能とするマウント部１２及びレンズ着脱機構と、レンズ着脱機構のレンズロック状態を解除するレンズ取外用操作部材１４と、他の外部機器３を背面側に接続させるために介在させる機器取付用アダプタ４を着脱可能とする装着部１９及びアダプタ着脱機構と、アダプタ着脱機構のアダプタロック状態を解除するアダプタ取外用操作部材１８とを具備し、レンズ取外用操作部材とアダプタ取外用操作部材とは隣接して配置され、レンズ取外用操作部材とアダプタ取外用操作部材との操作方向が同一方向となるように構成され、かつレンズ取外用操作部材及びアダプタ取外用操作部材は、レリーズ操作部材の配設位置に対して径方向外周に沿って角度９０度だけ離れた位置に配置されている。【選択図】図３
