Abstract
A solid-state imaging element including a well improves area efficiency while reducing malfunction of a circuit on the well. The solid-state imaging element includes a first well, a second well, a first circuit, and a second circuit. The first well contains an impurity having a polarity identical to a polarity of an impurity in a substrate. The second well contains an impurity having a polarity identical to the polarity of the impurity in the substrate and is disposed adjacent to the first well. The first circuit is disposed on the first well and generates noise in a predetermined period. The second circuit is disposed on the second well and generates noise in a period different from the predetermined period.
