The present invention aims at solving the problems of conventional methods for producing an 18F-labeled compound, that is, the problem of purification of a compound in a liquid phase synthesis method and the problem of an insufficient yield due to the reduction of reactivity in a solid phase synthesis method. There is provided a method for producing an 18F-labeled compound including: allowing a high molecular compound containing a residue of a precursor compound to be labeled and a residue of a phase transfer catalyst in the molecule thereof to react with 18F-； and removing the 18F-labeled compound from the high molecular compound.
