Analytical chip, analytical-chip unit, and analysis apparatus

摘要

An analytical chip is provided with a flow channel ( 5 ), whose section is in a closed shape and through which a fluid sample (Fs) is made to flow, for carrying out analysis regarding the fluid sample (Fs) based on interaction between a predetermined substance and a specific substance ( 61 ), which is placed facing said flow channel ( 5 ). The chip further has a projection member ( 9 b) attached to said flow channel ( 5 ). With this arrangement, it becomes possible to analyze the fluid sample (Fs) efficiently with high precision.
