A biochemical analysis unit includes a plurality of absorptive regions two-dimensionally formed so as to be spaced apart from each other by weaving a plurality of light shielding strips made of a material capable of attenuating radiation energy and a plurality of absorptive strips made of an absorptive material so that the light shielding strip is present between neighboring absorptive regions. According to the thus constituted biochemical analysis unit, it is possible to prevent noise caused by the scattering of electron beams (beta rays) released from a radioactive labeling substance from being generated in biochemical analysis data even in the case of forming in the biochemical analysis unit at a high density a plurality of spot-like regions selectively labeled with a radioactive labeling substance, thereby preparing the biochemical analysis unit, bringing the biochemical analysis unit into close contact with a stimulable phosphor layer to expose the stimulable phosphor layer to the radioactive labeling substance, irradiating the stimulable phosphor layer with a stimulating ray to excite the stimulable phosphor, photoelectrically detecting the stimulated emission released from the stimulable phosphor layer, and producing biochemical analysis data.
