Claim 6:
7. The all-solid secondary battery of claim 1,
wherein, a ratio of a packing density to a true density in each of the first solid electrolyte layer and the second solid electrolyte layer is about 0.6:1 or more,
the ratio of the packing density to the true density of the first solid electrolyte layer is less than a ratio of packing density to the true density of the second solid electrolyte layer, and
a difference between the ratio of the packing density to the true density of the first solid electrolyte layer and the ratio of the packing density to the true density of the second solid electrolyte layer is about 0.02:1 to about 0.05:1.
