Provided are a phosphoric acid diester salt, a production method therefor, a non-aqueous electrolyte for a power storage element, and a power storage element that are capable of, for example, suppressing the reduction of charge/discharge characteristics, and suppressing the increase of internal resistance after storage at a high temperature, of the power storage element. The present invention is characterized by being a phosphoric acid diester salt represented by chemical formula (1). (The Mn+ represents a hydrogen ion, an alkali metal ion, an alkaline earth metal ion, an aluminum ion, a transition metal ion, or an onium ion. The R1 and R2 are different from each other, and represent a hydrocarbon group having 1-10 carbon atoms, or a hydrocarbon group having between 1 and 10 carbon atoms, and having a least any one of a halogen atom, a heteroatom, or an unsaturated bond. The n represents valence.) |
