Summary:PROBLEM TO BE SOLVED: To produce high quality 1,4BG having good color tone and capable of being used as a raw material of PBT by efficiently removing impurities, which are mixed when 1,4BG derived from a biomass resource is produced in an industrial scale, to purify the 1,4BG derived from a biomass resource.SOLUTION: A method for producing 1,4BG comprises obtaining a crude 1,4BG-containing liquid from a purified raw material 1,4BG-containing liquid, obtained by removing at least a portion of each of fungus bodies, salt content and water from a fermentation medium, through a step for removing high boiling point components and/or low boiling point components by distillation and/or a step for converting unsaturated compounds to hydrides, and further, obtaining purified 1,4BG from a side fraction in a distillation step.
