Imaging apparatus, and imaging system

摘要

An embodiment is an imaging apparatus including a plurality of unit cells. The imaging apparatus includes a first conductive member electrically connected to gates of the plurality of first transfer transistors, a second conductive member electrically connected to gates of the plurality of second transfer transistors, a third conductive member disposed adjacently to the first conductive member in a same wiring layer as the first conductive member and electrically connected to a plurality of nodes each included in respective one of the plurality of unit cells, and a fourth conductive member disposed adjacently to the second conductive member in a same wiring layer as the second conductive member. An opposing length of the first conductive member and the third conductive member is longer than an opposing length of the second conductive member and the fourth conductive member.
