Abstract
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 (4A) in a tubular region injected with the liquid.
