Information on a larger number of base sequences can be obtained with a small amount of sample, and reaction detection can be efficiently performed by attaching a target nucleic acid to an appropriate probe from a plurality of types of nucleic acid probes. A reactive substance reaction method, a reaction apparatus thereof, and the like are provided. A detection probe pattern with a first solution (nucleic acid probe) is formed on a detection substrate, and after volatilization of a volatile substance in the first solution, a second solution (target) is formed on the detection probe pattern. A spot-like pattern is formed by the nucleic acid), and a hybridization reaction of the first solution and the second solution is caused. At this time, droplet ejection that does not contribute to the reaction is performed, and for example, a reference position pattern 113 for forming a pattern of both liquids at a desired position is provided.
