Zusammenfassung:	Disclosed is a manufacturing method of a sulfide-based solid electrolyte with a desired particle size by wet grinding. The present invention provides a manufacturing method of a sulfide-based solid electrolyte, the method comprising: a step of preparing a sulfide-based solid electrolyte material; and a micronization step of wet grinding the sulfide-based solid electrolyte material, wherein an organic solvent is used as a dispersion medium used in the wet grinding, and a ketone solvent is used as a dispersion stabilizer. Est divulgué un procédé de fabrication d'un électrolyte solide à base de sulfure, par broyage humide, présentant une taille de particules souhaitée. La présente invention concerne un procédé de fabrication d'électrolyte solide à base de sulfure, comprenant : une étape de préparation d'un matériau électrolyte solide à base de sulfure ; et une étape de micronisation consistant à broyer par voie humide le matériau électrolyte solide à base de sulfure, un solvant organique servant de milieu de dispersion utilisé dans le broyage humide, et un solvant cétonique servant de stabilisateur de dispersion. 습식 분쇄에 의하여 원하는 입도의 황화물계 고체전해질을 제조하는 제조 방법이 개시된다. 본 발명은 황화물계 고체전해질 재료를 준비하는 단계; 및 상기 황화물계 고체전해질 재료를 습식 분쇄하는 미립화 단계를 포함하고, 상기 습식 분쇄에 사용되는 분산매로서 유기 용매를 사용하고, 분산 안정제로서 케톤류 용매를 사용하는, 황화물계 고체전해질의 제조 방법을 제공한다.
