Abstract
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.
