To provide a liquid chemical injector capable of detecting a residual amount of a liquid chemical.SOLUTION: A liquid chemical injector 1 is assembled with: a liquid chemical tank 12 for retention of a liquid chemical; a volume pump 41 for injection of a liquid chemical retained in the liquid chemical tank 12 to an injection target; and a control unit 58 which drives the volume pump 41 as well as calculates a liquid chemical residual amount in the liquid chemical tank 12 by integrating a stroke number of the volume pump 41 from setting of the liquid chemical amount in the liquid chemical tank 12, multiplying an injection amount of the liquid chemical per one stroke to the integrated stroke number to calculate an integrated injection amount, and subtracting the integrated injection amount from a set liquid chemical amount in the liquid chemical tank 12.SELECTED DRAWING: Figure 4 【課題】薬液の残量を検出できる薬液注入装置を提供すること。【解決手段】薬液注入装置１は、薬液を貯留する薬液槽１２と、薬液槽１２に貯留された薬液を注入先へ注入する容積ポンプ４１と、容積ポンプ４１を駆動するとともに、薬液槽１２内の薬液量が設定されたときからの容積ポンプ４１のストローク数を積算し、積算したストローク数に１ストローク当たりの薬液の注入量を乗算することで、積算注入量を求め、設定された薬液槽１２内の薬液量から積算注入量を減算することで、薬液槽１２内の薬液残量を求める制御部５８と、を備える。【選択図】 図４
