Abstract
An object of the invention is to provide various flow cells and a method for manufacturing the same, in which formation of a groove on a substrate and formation of components such as an electrode, auxiliary parts such as a pump are not necessary. The inventive flow cells are capable of realize complicated chemical analysis or synthesis or the like. A channel of a porous member provided on a sample-incompatible substrate is formed; the porous member is composed of an air non-contact region having a network structure and an air contact region covering the air non-contact region and having a lower pore density than the air non-contact region; in which a capillary force to be generated within the porous member is a drive force for pumping a liquid.
