Summary:PROBLEM TO BE SOLVED: To provide a flow injection analyzing device with less reagent to be used and waste liquid wherein the size is reduced to allow carrying to a sample collecting field for detection. SOLUTION: A flow injection analysis flow-path A, a carrier pump 24 for feeding a sample to the analysis flow-path A by a carrier liquid, and a reagent pump 25 for feeding the reagent to a specified position of the analysis flow-path A, are provided. Here, the carrier pump 24 and the reagent pump 25 comprise a pump main body with a complete piston cylinder set having a capacity at least accommodating the carrier liquid and other liquid as required for a single analysis and a drive means for reciprocating the piston of pump main body, and a pump control means which operates the piston in liquid-sucking direction for drawing the liquid of required amount for continuous or intermittent operation in liquid-feeding direction is provided.
