To provide an operating liquid for a micropump that is capable of increasing a discharge pressure and a flow rate, and a micropump using the operating liquid.SOLUTION: An operating liquid for a micropump is provided which comprises an insulating liquid having a molecular weight of 1000 or less and a polymer compound having a number-average molecular weight of 10,000 or more. The content of the polymer compound in the total amount of the insulating liquid and the polymer compound is 0.01 wt.% to 10 wt.%. A micropump using the operating liquid is also provided.SELECTED DRAWING: Figure 1 【課題】吐出圧力と流量を増加させることができるマイクロポンプ用動作液体と、このマイクロポンプ用動作液体を用いたマイクロポンプとを提供する。【解決手段】分子量１０００以下の絶縁性液体と、数平均分子量１００００以上の高分子化合物とを含み、該絶縁性液体と該高分子化合物との合量における該高分子化合物の含有率が０．０１ｗｔ％～１０ｗｔ％であるマイクロポンプ用動作液体。このマイクロポンプ用動作液体を用いたマイクロポンプ。【選択図】図１
