    Abstract: A photodetector includes a first semiconductor layer including a light detection region and a peripheral region on a first surface on which light is incident. The light detection region is a region in which light detecting units are arrayed. The peripheral region is a semiconductor region disposed on the periphery of the light detection region and not including a light detecting unit. A density of a lattice defect or a concentration of impurity in a first layer region that is at least a part in a thickness direction of the peripheral region is higher than a density of a lattice defect or a concentration of impurity in a second layer region adjacent to the first layer region in a direction intersecting the thickness direction in the light detection region.
