To provide a micromixer maintaining and improving the mixing efficiency of a plurality of fluids while reducing pressure loss when supplying the plurality of fluids into flow passages, and to provide a microreactor including the same.
In this micromixer, a shaft body 4 is inserted into an axially long circular hole 3 formed in a body part 2, and flow passages for mixing the plurality of kinds of fluids while making the plurality of kinds of fluids flow in the shaft direction are formed in gaps between the inner circumferential surface 5 of the circular hole 3 and the outer circumferential surface 6 of the shaft body 4. The micromixer includes: a plurality of main flow passages 7a, 7b extending along the shaft direction parallel to each other; and a plurality of sub flow passages 8a-8g each extending in an oblique direction to the shaft direction and communicating the main flow passages with each other. By repeating that the fluids flowing through the main flow passages 7a, 7b are made to be branched/joined with the fluids of the other main flow passages 7b, 7a through the sub flow passages 8a-8g, the plurality of kinds of fluids are mixed.
