NOVELTY - A coating film (2) is formed on the surface of a base material (1) by coating (S1) a paste-form composition comprising sulfide solid electrolyte, substance capable of expressing viscosifying effect, and solvent. The coating film and to-be-transferred material (3) are contacted by pressing (S3). The coating film is transferred on the surface of to-be-transferred material by transfer process (S4), to obtain all-solid-state battery. The substance capable of expressing viscosifying effect has a functional group at both ends of principal chain.    USE - Manufacture of sulfide all-solid-state battery (claimed).    ADVANTAGE - The method enables manufacture of sulfide all-solid-state battery with high energy density and improved performance.    DETAILED DESCRIPTION - A coating film is formed on the surface of a base material by coating a paste-form composition comprising sulfide solid electrolyte, substance capable of expressing viscosifying effect, and solvent. The coating film formed on the surface of base material and to-be-transferred materials are contacted by performing pressing process. The coating film is transferred on the surface of to-be-transferred material by performing transferring process and peeling the base material after the pressing process, to obtain sulfide all-solid-state battery having a positive electrode layer, a negative electrode layer, and a solid electrolyte layer arranged between the positive and negative electrode layers. The substance capable of expressing viscosifying effect has a principal chain and a functional group at both ends of the principal chain. The functional group is a divalent organic group chosen from benzoyloxy group, benzoyl group, epoxy group, and primary amino group.
