A device for assay can evenly develop solution, and performs highly accurate and sensitive measurement. A first device part () maintains a second insoluble carrier () and a third insoluble carrier () in such a manner that they overlap with each other at a detection portion () of a first insoluble carrier (). These three carriers (), () and () are housed not in contact with each other. A pressing unit () having a pressing surface () that is parallel to the detection portion () is provided on an inner surface of the second device part () facing the detection portion (). The pressing surface () is displaced by being pressed toward the detection portion (), and presses, from the upper side of the first insoluble carrier (), the second insoluble carrier () and the third insoluble carrier () onto the first insoluble carrier (). The first device part () and the second device part () are joined together.

Method and device for assay

A plurality of kinds of liquids, which are of at least three kinds, containing (a) a test body solution containing at least one kind of an analyte, and (b) at least two kinds of liquids selected from the group consisting of a reagent solution, an amplifying solution, and a detecting solution, are fed to a detection site containing a specific binding substance with respect to the analyte. A qualitative analysis or a quantitative analysis of the analyte contained in the test body solution is thereby performed. Directions of liquid feeding of all of the plurality of the kinds of the liquids vary from one another, and the plurality of the kinds of the liquids are caused to intersect with one another at the detection site.
