An object is to provide a light irradiation apparatus irradiating a light to a sample in a reaction vessel while stirring the sample more efficiently. A rotating stage can rotate around a first axis that is a central axis thereof. A holding mechanism holds reaction vessels whose longitudinal directions are a direction of the central axis on a circumference around the first axis on the rotating stage at equal intervals. Rotation mechanisms hold bottoms of the reaction vessels and rotate the reaction vessels around second axes that are central axes of the reaction vessels, respectively. A light irradiation mechanism is disposed on the rotating stage and irradiates a light emitted from at least one light emitting diode to the reaction vessels from a predetermined direction.
