摘要： The invention provides an electrolyte solution capable of providing an electrochemical device that has a low internal resistance and excellent cycle characteristics and that is less likely to generate gas. The electrolyte solution contains lithium ethyl sulfate and ethyl sulfate. The lithium ethyl sulfate is present in an amount of 0.1 to 2.0% by mass relative to the electrolyte solution. The lithium ethyl sulfate and the ethyl sulfate give a mass ratio of the lithium ethyl sulfate to the ethyl sulfate of 80 to 1500.
