A method for producing biochemical analysis data includes the steps of collecting light selectively released from a plurality of light releasable regions two-dimensionally formed to be spaced apart from each other in a sample placed on a sample stage by a plurality of light guide member each of which is disposed to face one of the plurality of light releasable regions, leading the thus collected light to a light detector and photoelectrically detecting the light by the light detector. According to this method, it is possible to produce biochemical analysis data having high quantitative characteristics by photoelectrically detecting light emitted from a plurality of light releasable regions even in the case where the plurality of light releasable regions labeled with a labeling substance are formed in a sample at a high density.
