To fix a reagent and a reaction product while preserving position information of a target substance in a biological specimen as pre-processing for analyzing the target substance with high positional precision for each individual cell in the biological specimen To provide a biological specimen processing method and analysis method. A thin film composed of a porous body is brought into contact with a biological specimen containing cells or tissues, and a reagent solution is supplied from a non-contact surface side of the thin film to a specific area of the specimen by inkjet. A biological specimen reagent processing method for supplying, holding, and generating a reaction of the reagent limited to a cell level region in the biological specimen surface. Furthermore, the biological specimen analysis method of reading image information of a biological specimen, recording positional information, performing the reagent treatment method on a specific region in accordance with the image information, and then analyzing by microscopic observation or mass spectrometry.
