Provided is a method for manufacturing a solid electrolyte molded body, a composite, and a battery, which eliminates waste of a solid electrolyte forming material, reduces energy consumption, and the like. A first step S1 for preparing a solid electrolyte precursor solution 2X of any one of the formulas (1) and (2) and heating the solid electrolyte precursor solution 2X A second step S2 for firing, a third step S3 for applying pressure to the product obtained in the second step S2 to form a molded product, and a second firing for the molded product. And a fourth step S4 for forming a porous fired body.
