The invention discloses a cathode for an all-solid-state battery and a manufacturing method thereof. The cathode comprises a composite coated or dual coated cathode active material. The cathode includes: a composite particle including an inner core portion including a cathode active material and a shell portion coated on the inner core portion, and a sulfide-based solid electrolyte including a sulfide-based solid electrolyte, the sulfide-based solid electrolyte including a sulfide-based solid electrolyte, the sulfide-based solid electrolyte including a sulfide-based solid electrolyte, the sulfide-based solid electrolyte including a sulfide-based solid electrolyte, and the sulfide-based solid electrolyte. And the case portion comprises a first material represented by Chemical Formula 1 and a second material represented by Chemical Formula 2: [Chemical Formula 1] Li < 2 + x > B < x > O < 3 >, wherein x is 0 lt; x < = 1; [Chemical Formula 2] Li < 2 + y > PyO4, wherein y is 0 lt; y < = 1. The present invention can thin and uniformly coat a cathode active material using an inexpensive precursor material.
