摘要： The present invention is able to provide a method for producing an all-solid-state battery that has a solid electrolyte layer between a positive electrode layer and a negative electrode layer. This method for producing an all-solid-state battery is characterized by comprising: a step wherein a coating liquid is applied to at least one of the positive electrode layer and the negative electrode layer, said coating liquid containing a solid electrolyte solution, which is obtained by dissolving a solid electrolyte in a solvent, and fine particles which are insoluble in the solid electrolyte solution; and a step wherein the solvent is removed from the applied coating liquid, thereby having the solid electrolyte deposit on at least one of the positive electrode layer and the negative electrode layer.
