简介 Provided is a solution for dipping wherein, when producing a rare-earth superconductive composite metal oxide film by means of the dipping-pyrolysis process, cracks do not form in the heating process, which is performed for the purpose of removing organic components, even when the thickness of the rare-earth superconductive film produced in a single dip is 500nm or more, and without having to repeat the dipping and sintering process. A solution for producing a rare-earth superconductive film is made into a homogenous solution by dissolving, in a solvent formed by adding a polyhydric alcohol into a C1-8 univalent linear alcohol and/or water, a metal complex coordinated, in relation to a metal ion of a metallic species containing rare-earth elements, barium, and copper, with pyridine and/or at least one type of a tertiary amine, at least one type of a C1-8 carboxylic acid group, and, if needed, an acetylacetonate group.
