Summary:PROBLEM TO BE SOLVED: To provide a liquid supply system using a syringe pump, in which a liquid filling amount is accurate, and which avoids overflow of an ejection amount of a liquid ejected from an ejection unit at an initial operation.SOLUTION: A liquid supply system 1 includes: a syringe pump 11 for supplying a liquid to an ejection unit 10; a liquid supply unit 20 for supplying the liquid to the syringe pump 11; a first piping unit 12 for supplying the liquid from a liquid supply unit 20 side to the syringe pump 11; and a first valve 13 disposed at a position in front of the syringe pump 11 of the first piping unit 12. The liquid supply unit 20 includes: a tank 21 for storing the liquid to be supplied to the syringe pump 11; an auxiliary pump 22 for delivering the liquid in the tank 21 toward the syringe pump 11; a second piping unit 23 for supplying the liquid from the auxiliary pump 22 to a first piping unit 12 side; a second branch piping unit 24 branched from the second piping unit 23 in order to return the liquid to the tank 21; and a second valve 25 disposed in the second branch piping unit 24.SELECTED DRAWING: Figure 1 【課題】液体の充填量が正確で、かつ、噴出部から噴出される液体の動作初期の噴出量が多くなることを回避したシリンジポンプを用いた液体供給システムを提供する。【解決手段】本発明の液体供給システム１は、噴出部１０に液体を供給するシリンジポンプ１１と、シリンジポンプ１１に液体を供給する液体供給部２０と、液体供給部２０側からシリンジポンプ１１に液体を供給する第１配管部１２と、第１配管部１２のシリンジポンプ１１の手前の位置に設けられた第１バルブ１３と、を備え、液体供給部２０は、シリンジポンプ１１に供給される液体を貯蔵するタンク２１と、タンク２１の液体をシリンジポンプ１１に向けて送り出す補助ポンプ２２と、補助ポンプ２２から第１配管部１２側に液体を供給する第２配管部２３と、第２配管部２３から分岐され、液体をタンク２１に戻す第２分岐配管部２４と、第２分岐配管部２４に設けられた第２バルブ２５と、を備えている。【選択図】図１
