1. A microchannel device comprising a porous substrate, wherein a channel and channel walls are present in the porous substrate, wherein the channel is disposed in an area of the porous substrate, which is sectioned by the channel walls,
wherein the channel walls are hydrophobic and are configured to be formed by embedding at least one pore of the porous substrate with a resin, and the resin is configured to permeate the at least one pore and suppress leakage,
wherein the channel is sandwiched between the resin, and the resin is configured to not adhere to a region of the channel disposed between the resin, and wherein each of the channel walls contains a cyclic olefin copolymer that is a copolymer of an alkene and a cyclic olefin.
