Imaging device

An imaging device includes a photoelectric converter that converts incident light to charge, a semiconductor substrate that includes an element isolation region and a first impurity region of a first conductivity type, the first impurity region being electrically connected to the photoelectric converter, a plug that includes a first semiconductor, the plug being connected directly to the first impurity region, a pad that includes a second semiconductor, the pad being connected directly to the plug, and a first transistor that includes the first impurity region as one of a source and a drain and includes a first gate. The first impurity region is positioned between the first gate and a first portion of the element isolation region in plan view. The pad overlaps the first gate and the first portion in plan view.
