Abstract
The methods for producing microchannel chips of the present invention comprise the steps of shielding substrate surfaces on which groove-like channels have been formed, using a mask that exposes the channels, and then forming polymer membranes on the exposed surfaces of the substrates; and the step of laminating cover materials onto the side of the substrate surfaces on which the channels have been formed.
