Summary:A solid-state imaging device includes a plurality of photoelectric conversion parts; a floating diffusion part shared by the plurality of photoelectric conversion parts and converting charges generated in each of the plurality of photoelectric conversion parts into a voltage signal; a plurality of transmission parts respectively provided for the plurality of photoelectric conversion parts and transferring charges generated in the plurality of photoelectric conversion parts to the floating diffusion parts, respectively; a first transistor group electrically connected to the floating diffusion parts and having a gate and a source/drain arranged in a first layout configuration; and a second transistor group electrically connected to the floating diffusion parts and having a gate and a source/drain arranged in a second layout configuration symmetrical with the first layout configuration, and provided in a region different from the first transistor group. It is possible to suppress variations in characteristics such as sensitivity. 고체 촬상 장치는: 복수의 광전 변환부와; 상기 복수의 광전 변환부에 의해 공유되고, 상기 복수의 광전 변환부의 각각에서 생성된 전하를 전압 신호로 변환하는 플로팅 디퓨전부와; 상기 복수의 광전 변환부에 대해 각각 마련되고, 상기 복수의 광전 변환부에서 생성된 전하를 상기 플로팅 디퓨전부에 각각 전송하는 복수의 전송부와; 상기 플로팅 디퓨전부에 전기적으로 접속되며, 제 1의 레이아웃 구성으로 배치된 게이트 및 소스/드레인을 갖는 제 1 트랜지스터군; 및 상기 플로팅 디퓨전부에 전기적으로 접속되고, 상기 제 1의 레이아웃 구성과 대칭적인 제 2의 레이아웃 구성으로 배치된 게이트 및 소스/드레인을 가지며, 상기 제 1 트랜지스터군과는 다른 영역에 마련된 제 2 트랜지스터군을 구비한다.
