The whole surfaces (10a, 20a) are made hydrophobic. An upper channel (11) and a lower channel (21) to be stacked on each other to form a flow path (2) are formed in the surfaces (10a, 20a), respectively. A first through hole (12) and a second through hole (13) are formed at predetermined positions in the upper plate (10). The upper plate (10) and lower plate (20) are stacked on each other, and are secured by an upper pressure-contact member (30), a lower pressure-contact member (40) and bolts (51). A microfluidic device capable of preventing leakage of fluid can thereby be manufactured without undergoing a step of irreversible integration. Preferably, the plates are made of Fe-Ni alloy, and hydrophobicity is achieved by boron nitride obtained as a result of surface segregation. The channels are formed by etching.
