Micro analysis chip and fabrication method thereof

A micro analysis chip comprises an inlet and a fluid flow path communicating thereto. The fluid flow path comprises a first flow path, a second flow path, and a third flow path arranged continuously along a longitudinal direction of the fluid flow path. An antibody is bound on at least one peripheral surface selected from the group consisting of peripheral surfaces of the second and third flow paths. A cross-sectional area of the third flow path is constant or increased monotonically along a direction X from the second flow path toward the third flow path. A cross-sectional area of the second flow path is increased monotonically along the direction X from the one end to the other end of the second flow path. A cross-sectional area of the first flow path is larger than a cross-sectional area at the one end of the second flow path.
