A secondary battery includes a positive electrode, a negative electrode, electrolyte, and an intermediate layer, which is arranged between the positive electrode and the negative electrode and includes at least one from polyphosphate, melamine salt, melamine derivative represented by Chemical formula (1), metal hydroxide, and metal hydrate. The intermediate layer is partially included in the positive electrode, the negative electrode, or both. In Chemical formula 1, Each of R1 to R6 is one from a hydrogen group (-H), a monovalent hydrocarbon group, a hydrocarbon group containing a monovalent hydroxyl group, a group bound to make one or more monovalent hydrocarbon groups which are bound with one or more oxygens (-O-) be monovalent as a whole, a group bound to make one or more monovalent hydrocarbon groups including a hydroxyl group which are bound with one or more oxygens (-O-) be monovalent as a whole, and a group bound to make two or more of those be monovalent as a whole.
