Field: Micro-structural and nano-technology (Chemistry)
Classification: CPC B | IPC B

Claim 0:
1. A method for producing a microchannel device that has a channel sandwiched between channel walls formed in an inside of a porous substrate, comprising:
placing a first hydrophobic resin on a surface of the porous substrate to form a channel pattern on the surface of the porous substrate; and
melting the first hydrophobic resin by heat to allow the first hydrophobic resin to permeate into the inside of the porous substrate, thereby forming a channel wall in the inside of the porous substrate,
wherein when the channel wall is formed, the first hydrophobic resin is allowed to permeate at a temperature at which a storage elastic modulus G′ of the first hydrophobic resin is 14 Pa or lower, and a loss elastic modulus G″ thereof is 10 Pa or higher.
