OPTICAL SENSOR AND MANUFACTURING METHOD THEREOF

An optical sensor includes: a lower substrate; a plurality of lower electrodes on the lower substrate; an organic photoelectric conversion layer that is provided in common on the plurality of lower electrodes and includes a hole transport layer, an active layer, and an electron transport layer in this order from the lower substrate side; a conductive adhesive that is provided between each of the plurality of lower electrodes and the organic photoelectric conversion layer and electrically connects each of the plurality of lower electrodes to the organic photoelectric conversion layer; a light-transmitting upper electrode provided on the organic photoelectric conversion layer; and a light-transmitting upper substrate provided on the upper electrode.
