The purpose of this invention is to provide a light-receiving element and the like in which light can be absorbed and transmitted in a simpler manner. Said light-receiving element has the following: a lens section that collects inputted light and outputs said light from an output surface; an absorption layer that is placed on the output surface of the lens section, absorbs some of the collected light, and transmits the remainder; and a detection layer that is laminated to the absorption layer, and on the basis of the intensity of the light absorbed by the absorption layer, detects the intensity of the light outputted by the lens section. |
