To provide an imaging device capable of reducing noise.SOLUTION: An imaging device is provided with a layered structure in which a first substrate, a second substrate and a third substrate are stacked in order. The first substrate has sensor pixels which perform photoelectric conversion and output a signal charge. The second substrate has a first signal processing circuit which includes a first analog transistor and forms a readout circuit that outputs a pixel signal based on the signal charge. The third substrate has a logic circuit that processes the pixel signal.SELECTED DRAWING: Figure 2 【課題】ノイズを低減することができる撮像装置を提供する。【解決手段】本開示の一実施の形態の撮像装置は、光電変換を行うとともに信号電荷を出力するセンサ画素を有する第１基板と、信号電荷に基づく画素信号を出力する読み出し回路を構成し第１のアナログトランジスタを含む第１の信号処理回路、を有する第２基板と、画素信号を処理するロジック回路を有する第３基板とが順に積層された積層構造を備える。【選択図】図２
