Method for producing microchannel, and microchannel
Provided is a method for producing a microchannel including an approximately circular cross section with neither a joined surface nor an inlet in a smaller number of steps than has been conventional. The method for producing a microchannel includes the steps of forming a layer of an uncured curable resin ( 2 ) on a substrate ( 1 ), inserting into the curable resin a needle body ( 3 ) that can inject a liquid ( 4 ), injecting a liquid in a tubular shape into the curable resin via the needle body while moving the needle body, extracting the needle body from the curable resin, and curing the curable resin to form a channel ( 4 A) in a tubular region injected with the liquid.
1. A method for producing a microchannel, comprising the steps of:
forming a layer of an uncured curable resin on a substrate;
inserting into the curable resin a needle body that can inject a liquid;
injecting a liquid in a tubular shape into the curable resin via the needle body while moving the needle body;
extracting the needle body from the curable resin; and
curing the curable resin to form a channel in a tubular region injected with the liquid.
2. The method according to claim 1 , wherein the channel is a channel comprising an approximately circular cross section without any joined surfaces.
3. The method according to claim 1 , further comprising the step of removing a part of the cured curable resin to extract the liquid confined within the curable resin.
4. The method according to claim 1 , wherein the liquid is a liquid crystal.
