Provided are a light-emitting device and a photovoltaic cell having excellent characteristics. A light-emitting device (
10
) includes a cathode (
34
), an anode (
32
), a light-emitting layer (
50
) interposed between the cathode (
34
) and the anode (
32
), and an electron injection layer (
44
) provided between the cathode (
34
) and the light-emitting layer (
50
) and connected to the cathode (
34
), in which at least one of the anode (
32
) and the cathode (
34
) contains a conductive material having an aspect ratio of 1.5 or more, and the electron injection layer (
44
) contains an organic compound having at least one of an ionic group and a polar group.
