Lithium secondary battery

A lithium secondary battery comprising an electroytic layer, a positive electrode, and a negative electrode that is made of a lithium-containing material, in which battery:

• (a) the electrolytic layer is made of an inorganic solid electrolyte;
• and
• (b) the positive electrode contains an organic high polymer, wherein the electrolytic layer contains at least one type selected from the group consisting of oxygen, nitrogen, sulfide, and oxynitride;
• and
• (a) the sulfide is composed of at least one type selected from the group consisting of Li2S, a compound between Li2S and SiS2, a compound between Li2S and GeS2, and a compound between
