    Abstract: An object of the present invention is to provide a method for inspecting a treatment liquid to determine whether the treatment liquid, when used as a developer or a rinsing liquid, allows formation of a resist pattern with reduced variation in line width. Another object of the present invention is to provide a method for producing a treatment liquid.
    The method for inspecting a treatment liquid according to the present invention is a method for inspecting a treatment liquid including an aliphatic hydrocarbon solvent and has a step A1 of acquiring measurement data of a content of an acid component in the treatment liquid, the acid component being at least one selected from the group consisting of carboxylic acids having a hydrocarbon group having 1 to 3 carbon atoms and formic acid, and a step A2 of determining whether the measurement data acquired in the step A1 falls within a preset allowable range.
