Abstract
According to a photodetector includes a first light detection layer and a reflective layer. The first light detection layer has a first surface and a second surface on a side opposite to the first surface. The first light detection layer includes a first light detection area including a p-n junction of a p-type semiconductor layer containing Si and an n-type semiconductor layer containing Si. The reflective layer arranged on a second surface side of the first light detection layer so as to be opposed to the first light detection area. The reflective layer reflects at least part of light in a near-infrared range.
