[claim2]
2.

Wherein the alkali metal is, there by Li or Na  The AX is, if A is Li, LiI, LiBr, LiCl, LiF, LiBF4, LiBH4, Li2SO4, Li3BO3, Li3PO4, Li2O, Li2Se, Li3N, Li3P, Li3As, Li3Sb, LiPF6, LiAsF6, LiClO4, LiNO3, Li2CO3, LiCF3SO3, LiCF3COO, is selected from LiN (SO2F) 2 and LiN (CF3SO2) 2, when a is Na, NaI, NaBr, NaCl, NaF, NaBF4, NaBH4, Na2SO4, Na3BO3, Na3PO4, Na2O, Na2Se, Na3N, Na3P , Na3As, Na3Sb, NaPF6, NaAsF6, NaClO4, NaNO3, Na2CO3, NaCF3SO3, NaCF3COO, NaN (SO2F) 2 and NaN (CF3SO2) positive electrode for all-solid-state secondary battery according to claim 1, which is selected from the 2.
[claim3]
3.

The A2S · AX is, the A2S and AX 99: 1 ~ 20: positive electrode for all solid state secondary battery according to claim 1 in a proportion of 80 (molar ratio).
[claim4]
4.

Furthermore a conductive material made of a carbon material, wherein for a positive electrode active material 100 parts by weight, the positive electrode for all solid state secondary battery according to claim 1 in a proportion of from 0.1 to 50 parts by weight.
[claim5]
5.

The all solid state secondary battery positive electrode, a solid electrolyte layer and the laminate of the negative electrode selection, similar to the solid electrolyte layer A2S · MxSy (A above, M is P, Si, Ge, B, Al, Ga, is, x and y, depending on the type of M, comprise an integer) that gives the stoichiometric ratio as the electrolyte, wherein the positive electrode, for all-solid secondary battery according to claim 1 which does not include the electrolyte the positive electrode of.
[claim6]
6.

It claims a positive electrode manufacturing method according to claim 1, a positive electrode manufacturing method for all solid state secondary battery to obtain an A2S · AX by subjecting the A2S and AX to mechanical milling.
[claim7]
7.

The mechanical milling process, using a planetary ball mill 50 to 700 revolutions / minute, 0.1 to 30 hours, to claim 6 which is performed under the condition of 1 ~ 100kWh / 1kg (total amount of the A2S and AX) a positive electrode manufacturing method for all solid state secondary battery according.
[claim8]
8.

The includes a positive electrode conductive material further comprising a carbon material, said positive electrode, fabrication of the positive electrode for all solid state secondary battery according to claim 6 obtained by subjecting the A2S · AX and a conductive material to mechanical milling Method.
[claim9]
9.

A positive electrode according to claim 1, similarly to the A2S · MxSy (A above, M is selected P, Si, Ge, B, Al, from Ga, x and y, depending on the type of M, stoichiometry all-solid secondary battery including a solid electrolyte layer that is represented by an integer) that gives the logical ratio.
