To provide a multi-layered imaging device capable of varying sensitivity.SOLUTION: The imaging device of the present disclosure has a pixel and a voltage application circuit. The pixel includes an upper electrode, an auxiliary electrode, a pixel electrode that collects holes as signal charges, an auxiliary electrode, and a photoelectric conversion layer positioned between the upper electrode and the pixel electrode. The voltage application circuit can selectively apply the first voltage and the second voltage to the auxiliary electrode. The first voltage and the second voltage are smaller than the voltage applied to the upper electrode.SELECTED DRAWING: Figure 1 【課題】感度が可変である積層型の撮像装置を提供する。【解決手段】本開示の撮像装置は、画素と、電圧印加回路とを有する。画素は、上部電極と、補助電極と、信号電荷として正孔を収集する画素電極と、補助電極および上部電極と画素電極との間に位置する光電変換層とを含む。電圧印加回路は、補助電極に対し、第１の電圧と第２の電圧とを選択的に印加可能である。第１の電圧および第２の電圧は、上部電極に印加される電圧よりも小さい。【選択図】図１
