To provide an imaging device capable of suppressing parasitic capacitance of wiring in floating diffusion.SOLUTION: In order to solve the above-mentioned problem, provided according to the present disclosure is an imaging device constituted by a plurality of pixels. A first pixel among the plurality of pixels comprises a first photoelectric conversion element, a first electrical storage unit, and a first transfer element that imposes a conducting state or a non-conducting state between the first photoelectric conversion element and the first electrical storage unit. A second pixel adjacent to the first pixel among the plurality of pixels comprises a second amplification element that amplifies an image signal based on a charge accumulated in the first electrical storage unit due to photoelectric conversion performed by the first photoelectric conversion element.SELECTED DRAWING: Figure 3 【課題】フローティングディフュージョンにおける配線の寄生容量の抑制が可能な撮像装置を提供する。【解決手段】上記の課題を解決するために、本開示によれば、複数の画素で構成される撮像装置であって、複数の画素内の第１画素は、第１光電変換素子と、第１畜電部と、第１光電変換素子と、第１畜電部との間を導通状態又は非導通状態にする第１転送素子と、を有し、複数の画素内の第１画素に隣接する第２画素は、第１光電変換素子の光電変換により第１畜電部に蓄電された電荷に基づく画像信号を増幅する第２増幅素子を有する、撮像装置が提供される。【選択図】図３
