Provided is a method for fabricating a microchip for nucleic acid amplification reaction that is capable of simple and highly accurate analysis. Provided is a method for fabricating a microchip for nucleic acid amplification reaction, the method including a solidification step of drying a reagent solution including at least a part of substances required for a nucleic acid amplification reaction, and a containment step of arranging the reagent solution including the solidified substance in wells that serve as a reaction site for a nucleic acid amplification reaction. In the microchip for nucleic acid amplification reaction fabricated by the fabrication method, since substances required for the nucleic acid amplification reaction are contained by being solidified, non-specific amplification is suppressed in a nucleic acid amplification reaction, which enables highly accurate analysis.
