Abstract: The light detector includes: a substrate including at least one light receiving area and a light incident surface on which light is incident; and a meta-lens formed on the light incident surface of the substrate to focus the light incident on the light incident surface. When viewed from the thickness direction (Z-axis direction) of the substrate, the meta-lens is formed so as to overlap both an adjacent region adjacent to the light receiving area and a peripheral region that is continuous with the adjacent region and is a region inside the light receiving area along the outer edge of the light receiving area. When viewed from the Z-axis direction, a non-forming region in which the meta-lens is not formed is provided in a region overlapping a central region of the light receiving area in the light incident surface.
