摘要：
In a photoelectric conversion device, the meta-surface includes a first antenna portion, a first bias portion, a second antenna portion, and a second bias portion. The first antenna portion extends in a first direction and emits an electron in response to incidence of the electromagnetic wave. The first bias portion faces the first antenna portion and is configured to generate an electric field having a component in the first direction between the first bias portion and the first antenna portion. The second antenna portion extends in a second direction intersecting the first direction and emits an electron in response to incidence of the electromagnetic wave. The second bias portion faces the second antenna portion and is configured to generate an electric field having a component in the second direction between the second bias portion and the second antenna portion.
