Abstract: An optical device includes a nanostructure body which induces surface plasmon resonance when irradiated with light, an alloy layer which is in contact with the nanostructure body and which has a lower work function than the nanostructure body, and an n-type semiconductor which is in Schottky contact with the alloy layer. The nanostructure body is composed of one selected from the group consisting of elemental metals, alloys, metal nitrides, and conductive oxides. The alloy layer is composed of at least two metals.
