PCT No. PCT/JP95/00458 Sec. 371 Date Mar. 8, 1996 Sec. 102(e) Date Mar. 8, 1996 PCT Filed Mar. 17, 1995 PCT Pub. No. WO95/26031 PCT Pub. Date Sep. 28, 1995The present invention relates to a solid electrolyte thin film and a manufacturing method for the same. The solid electrolyte thin film of the present invention comprises yttrium stabilized zirconia and is characterized in that the thickness of the film is 10 to 50 mu m. In an embodiment, 80% or more of the surface area of the film is occupied by crystals having a crystal grain size of 6 to 18 mu m. The present invention also includes a method for producing a solid electrolyte thin film comprising a sintered body of solid electrolyte powders. The method includes regulating the grain size of said solid electrolyte powders in the range of 0.1 to 5.0 mu m; preparing a slurry solvent by mixing a binder and other materials with a solvent containing 10 to 80 wt % of a low volatile solvent, and mixing the slurry solvent with the solid electrolyte powder; and coating the obtained slurry onto a substrate. The slurry composition is prepared so that it has a viscosity in the range of 1 to 500 cps.
