PROBLEM TO BE SOLVED: To provide a technique for reducing shading occurring in a solid-state imaging device.SOLUTION: A solid-state imaging device includes: a plurality of pixels which each have a photoelectric conversion element and a transfer transistor and are arranged in an array; a drive circuit configured to supply control signals to the transfer transistors of the plurality of pixels; and a plurality of drive lines connecting the transfer transistors of the plurality of pixels and the drive circuit. The plurality of pixels include a first pixel and a second pixel connected to the same drive line. The distance from the drive circuit to the first pixel is longer than the distance from the drive circuit to the second pixel. The driving force of the transfer transistor of the first pixel is lower than the driving force of the transfer transistor of the second pixel. 【課題】固体撮像装置で発生するシェーディングを低減するための技術を提供する。【解決手段】固体撮像装置は、各画素が光電変換素子と転送トランジスタとを有し、アレイ状に配された複数の画素と、複数の画素の転送トランジスタに制御信号を供給するように構成された駆動回路と、複数の画素の転送トランジスタと駆動回路とを接続する複数の駆動線とを備える。複数の画素は、同一の駆動線に接続された第１画素と第２画素とを含む。駆動回路から第１画素までの距離は、駆動回路から第２画素までの距離よりも遠い。第１画素の転送トランジスタの駆動力は、第２画素の転送トランジスタの駆動力よりも低い。【選択図】図３
