The invention is achieved by feeding a reagent using centrifugal force, without providing a valve for controlling the flow rate of the reagent in the reagent flow path. A chemical analyzer is used which comprises a structure that is supported so as to be rotatable, said structure comprising a capturing section for capturing specific chemical substances from a specimen, specimen containers and reagent containers including washing solution containers. The washing solution containers and the other reagent containers comprise a liquid outlet port which is provided at the side opposite to the rotation center side, and the capturing section is held in the structure, closer to the outer periphery side than the specimen container and washing solution and the other reagent containers, and a flow path is provided, with a bent flow path portion which returns to the rotation center side, and which at a particular stage prevents the flow of liquid from the washing solution containers to the capturing section, and at another stage, forms the liquid flow due to the centrifugal force from the rotation of the structure.
