Abstract
According to one embodiment, a light detector includes a plurality of elements, a plurality of insulating parts, and an intermediate part. The plurality of elements are arranged along a first direction and a second direction. The first direction and the second direction cross each other. Each of the plurality of elements includes a first semiconductor region and a second semiconductor region. The first semiconductor region is of a first conductivity type. The second semiconductor region is located around the first semiconductor region in a first plane. The first plane is along the first and second directions. The second semiconductor region is of a second conductivity type. The plurality of insulating parts are located respectively around the plurality of elements in the first plane. The intermediate part is located around the plurality of insulating parts in the first plane. The intermediate part includes a semiconductor.
