Zusammenfassung:Provided are a negative electrode layer for an all-solid secondary battery, and an all-solid secondary battery including the same, the negative electrode layer comprising a negative electrode current collector and a first negative electrode active material layer including a carbon-based material, wherein the carbon-based material includes a mixture of amorphous carbon black and crystalline carbon black, and satisfies that the D peak to G peak intensity ratio of the amorphous carbon black, obtained by Raman analysis, is 1.5 or more, and the D peak to G peak intensity ratio of the crystalline carbon black, obtained by Raman analysis, is greater than 0.5 and less than 1.5.
