Micro flow channel chip and method for producing flow channel chip

Abstract

Provided is a method for producing a micro flow channel chip that is used for a treatment or analysis of a liquid sample, the method being capable of producing a micro flow channel chip with high shape accuracy and high efficiency. The method includes a step of forming a groove on one surface of a base material; a lamination step of forming an adhesive resin layer on at least one surface of a resin film, and thereby obtaining a first laminate; and an adhesion step of arranging the surface of the base material where a groove has been formed and the adhesive resin layer of the first laminate to face each other, and bonding the base material and the first laminate such that the adhesive resin layer covers the groove, in which the glass transition temperature of the adhesive resin layer is 25° C. or lower.
