Abstract

A method for producing (meth)acrylic acid, comprising specific steps. In the method, a liquid containing a discharged liquid that is discharged in at least one step among the aforementioned steps is used as a collected liquid, the collected liquid is held for 1 to 60 days, and the held liquid is fed to the extraction step. Fig 1.
