Claim Text:
1. A disc-like assay chip, comprising an internal space, wherein a centrifugal force is applied to move a liquid existing in the internal space to a desired position in the internal space, and the internal space comprises: a first groove, used for accommodating a first liquid; a second groove, used for accommodating a second liquid; a third groove, used for accommodating a third liquid; a fourth groove, used for accommodating a fourth liquid; a fifth groove, disposed at a side closer to a peripheral portion of the assay chip than the first groove, the second groove, the third groove and the fourth groove; a sixth groove, disposed at a side closer to the peripheral portion of the assay chip than the fifth groove; a first flow path, for connecting the first groove and the fifth groove; a second flow path, for connecting the second groove and the fifth groove; a third flow path, for connecting the third groove and the fifth groove; a fourth flow path, for connecting the fourth groove and the fifth groove; and a fifth flow path, for connecting the fifth groove and the sixth groove; wherein a transversal cross-sectional area of the first flow path and that of the second flow path are greater than that of a transversal cross-sectional area fifth flow path, a transversal cross-sectional area of the fifth flow path is greater than that of the third flow path, and a transversal cross-sectional area of the third flow path is greater than that of the fourth flow path.
