Abstract
A sensor chip according to an embodiment of the present disclosure includes a pixel. The pixel includes a photoelectric converter, a light reflector, and a light collector. The photoelectric converter includes a light entering surface which light enters and a multiplication region in which avalanche multiplication of carriers is caused by a high electric-field region. The light reflector is provided to oppose a surface, of the photoelectric converter, on an opposite side to the light entering surface. The light collector is provided between the photoelectric converter and the light reflector.
