A novel positive electrode active material for an alkaline earth metal secondary battery and an alkaline earth metal secondary battery using the same are provided. A non-aqueous electrolyte for an alkaline earth metal secondary battery contains a non-aqueous solvent, an alkaline earth metal cation, an organic molecule coordinated to the alkaline earth metal cation, and an anion. The organic molecule is a carbonate ester, a carboxylic ester, a phosphate ester, or a sulfonate ester. [Selection] Figure 1 |
