An object of the present invention is to suppress the generation of air bubbles in a flow channel and the deformation of an analysis chip, and reduce the amount of a liquid sample to be used, so that the analysis of a liquid sample can be performed efficiently and accurately. Provide an analysis chip. A liquid sample (Fs) is circulated through a flow path having a closed cross-sectional structure, and analysis on the liquid sample (Fs) is performed based on an interaction between a predetermined substance and a specific substance fixed on the flow path. In the analysis chip used in (1), the flow path has a convex member 9b. [Selection diagram] Fig. 1 |
