In a photoelectric conversion device, the potential control unit controls electric potentials applied to the meta-surface. The meta-surface includes a plurality of patterns which are space away from each other. The plurality of patterns include an antenna portion and at least one bias portion. The antenna portion extends in a predetermined direction and emits the electron in response to incidence of the electromagnetic wave. The potential control unit switches a first state and a second state by controlling the electric potentials applied to the plurality of patterns. In the first state, a component of an electric field from the bias portion toward the antenna portion in a predetermined direction is positive. In the second state, a component of an electric field from the bias portion toward the antenna portion in the predetermined direction is negative.

Provided are an automatic analyzer and an optical measurement method for correcting a variation in the multiplication factor of a photoelectric element with high accuracy. The automatic analyzer comprises: a photoelectric element which generates electrons by light and outputs a current signal; a voltage application unit which applies a voltage to the photoelectric element; and a processing unit which corrects a variation in the multiplication factor of the photoelectric element, wherein the photoelectric element outputs a pulse signal as the current signal, and the processing unit corrects the variation in the multiplication factor on the basis of the pulse area of the pulse signal.
