A solid electrolyte composed of Li, O, P and a transition metal element is disclosed. In such a solid electrolyte, decrease in valence of phosphorus atom can be suppressed since a transition element T is more preferentially reduced than phosphorus. Consequently, decomposition of the solid electrolyte ascribed to decrease in valence of phosphorus atom is suppressed, and thus the ionic conductance is kept high even in a wet atmosphere. |
