Provided is a microchannel device manufacturing method by which a channel having high hydrophobicity, high solvent resistance, and resistance to heat and damage can be formed with high accuracy on demand, such that a microchannel device is manufactured at low cost with high productivity, wherein a channel pattern made of a hydrophobic resin is formed on a porous substrate via an electrophotographic method, and then the channel pattern is melted by heat and permeated into the porous substrate to form a flow path inside the porous substrate. |
