PROBLEM TO BE SOLVED: To provide a microreactor in which a mixed reagent obtained by mixing a plurality of reagents is reacted with a sample, the time to mix liquids such as reagents, the mixing ratio of liquids and the pressure when a liquid is sent can be controlled with high precision and an air bubble can be prevented from being interposed between the liquid and a driving liquid when the liquid is sent while being pushed by the driving liquid. SOLUTION: An injection port 34b for injecting the driving liquid into a housing chamber 34a and an outlet 34c through which the reagent is pushed from the housing chamber 34a by the injected driving liquid are arranged in each of a plurality of reagent housing parts 33 composed of housing chambers in which the plurality of reagents are housed individually. The driving liquid from an external pump 12 is injected into the housing chamber 34a through an opening 32 of the microreactor 1, which is communicated with the injection port 34b. A flow passage 46 for venting air, which branches from a flow passage 45 and the terminal end of which is opened to the outside, is arranged on the flow passage 45 by which the injection port 34b is communicated with the opening 32.
