Abstract
According to one embodiment, a light detector includes a junction region, a first insulating portion, and a quenching part. The junction region includes a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type. The second semiconductor region is provided on the first semiconductor region and forms a p-n junction surface with the first semiconductor region. The first insulating portion has an inclined surface inclined with respect to a first direction perpendicular to the p-n junction surface and includes void. The inclined surface is provided at a same height as at least a portion of the junction region and crosses the second direction from the junction region toward the first insulating portion. The quenching part is electrically connected to the second semiconductor region.
