The present invention provides a method for producing an electrolyte solution which can contain a high concentration of microbubbles, and a method for producing a microbubble-containing solvent which can be used for preparing the electrolyte solution, by suppressing decrease in microbubbles during filtration. A method for producing a microbubble-containing electrolyte solution of the present invention includes the steps of: filtrating a microbubble-containing solvent with a filter medium; and preparing an electrolyte solution from an obtained filtrate, wherein a cation concentration in the microbubble-containing solvent is less than 20 mmol/l, and the method satisfies at least one of the following conditions (1), (2) and (3): nCondition (1): na microbubble density in the microbubble-containing solvent is 1 × 10 6 bubbles/ml or more; nCondition (2): nthe method includes the step of preparing a microbubble-containing solvent by introducing microbubbles into a solvent; and nCondition (3): na microbubble density in the electrolyte solution is 1 × 10 5 bubbles/ml or more. |
