Claim:
1. A method for manufacturing a lithium ion conductive solid electrolyte comprising: preparing a slurry comprising lithium ion conductive glass or glass-ceramic powder as a main component and comprising also at least an organic binder and water used as a solvent, forming the slurry to a greensheet, isotropically pressing the greensheet so as to make the greensheet dense, and sintering the greensheet with variation in thickness of the greensheet being within a range from +10% to −10% relative to mean value of distribution of thickness of the greensheet, wherein the solid electrolyte has porosity of 10 vol % or less, and the solid electrolyte has thickness of 200 μm or below wherein the glass or glass-ceramic powder comprises lithium, silicon, phosphorus and titanium, and average particle diameter of the glass or glass-ceramic powder is 20 μm or below.
