Abstract
There is provided a photoelectric conversion device utilizing surface plasmons, including: a plate-shaped light receiving portion which made of metal, provided on a most superficial surface of the photoelectric conversion device, and having a front surface and a rear surface so as to receive incident light at the front surface; a slot-shaped slit provided in the front surface of the light receiving portion; and a voltage detection portion adapted to measure an electric potential at the front surface of the light receiving portion; wherein the incident light is caused to excite surface plasmons through the slit, and an electric potential at the front surface of the light receiving portion induced by the surface plasmons is measured by the voltage detection portion.
