Provided are a method for producing an electrolyte solution capable of containing a high concentration of microbubbles by suppressing the reduction of microbubbles during filtration, and a method for producing a microbubble-containing solvent that can be used to prepare the aforementioned electrolyte. The method for producing a microbubble-containing electrolyte solution of the present invention includes the steps of: a filtration step of filtering a microbubble-containing solvent with a filter material; and a production process of preparing an electrolyte solution from the obtained filtrate, wherein the microbubble-containing solvent is The cation concentration is less than 20 mmol/l, and the production method satisfies at least one of the following conditions (1), (2), and (3): Condition (1): the micro-bubble-containing solvent The density of the air bubbles is 1×10 6 cells/ml or more; Condition (2): A solvent preparation step including a process for preparing a microbubble-containing solvent by introducing microbubbles into a solvent; Condition (3): The microbubbles in the electrolyte solution The density is 1×10 5 pieces/ml or more. |
