摘要： An analysis chip for quantitative analysis by using a competitive reaction is provided. The analysis chip for analyzing a target substance to be identified in a liquid sample includes a base, and a flow path formed on the base. The flow path includes an introduction portion, for introducing the liquid sample; a reaction portion, disposed at a downstream side of the introduction portion, for subjecting the liquid sample to a competitive reaction; a discharge portion, disposed at a downstream side of the reaction portion; and a blocking portion, disposed between the reaction portion and the discharge portion, for inhibiting the flow of the liquid sample from the reaction portion to the discharge portion. The reaction portion accommodates a carrier prefixed with a specific binding substance for specifically binding the target substance to be identified or a competitive substance of the target substance to be identified.
