In a microdevice in which a plurality of fluids respectively passing through a separate introduction channel are merged in a merging section in a micro space to mix the fluids and the mixed fluids are discharged from the merging section via a discharge channel, a tip section of each of the introduction channels comprises a tapered contraction section so as to contract a flow of fluid, the introduction channels are disposed so that central axes of the introduction channels do not intersect at one point each other, and the merging section is formed of a space surrounded with edges of the contraction sections of respective introduction channels. Thereby, reacting fluids can be mixed rapidly each other, and contamination of air bubbles into the whole fluid can be suppressed by narrowing a dead space of a discharge channel immediately after the merging section.
