PROBLEM TO BE SOLVED: To provide a slurry which can steadily manufacture a solid electrolyte membrane of a uniform and fine ceramic nature even when a screen printing method or a normal painting method is adopted, and a uniform and fine solid electrolyte membrane using the slurry. SOLUTION: The solid electrolyte membrane forming slurry contains (A) a solid electrolyte membrane forming oxide powder which has an average particle size of 0.1-1 μm and a particle size of 3 μm or less of its 90 volume %, and (B) as a binder, an alkyl(meth)acrylate group copolymer which is made of a copolymer comprising as a primary monomer content an alkyl(meth)acrylate having carbon number of 1-20 for 40-95 mass % and which has one or more of acid number, amine number and hydroxy group number, with either number being 1-80, and a solid electrolyte membrane using this slurry is provided. |
