METHOD OF PRODUCING ANALYTICAL TOOL

摘要

The present invention relates to a method of producing an analytical tool comprising a substrate (2) made of a polymer material and formed with a groove (20) for moving a sample liquid, and a cover bonded to the substrate (2) to cover the groove (20). The method includes hydrophilically treating an inner surface of the groove (20). The hydrophilization includes a primary modifying step for primarily modifying characteristics of the inner surface of the groove (20) by bringing a modifying gas into contact with the inner surface of the groove (20), and a secondary modifying step for secondarily modifying the characteristics of the inner surface of the groove (20). <IMAGE>
