A secondary battery includes: a cathode; an anode; an electrolytic solution; and an interlayer arranged between the cathode and the anode and including one or more of a polyphosphate salt, a melamine salt, a melamine derivative represented by chemical formula 1, a metal hydroxide, and a metal hydrate, wherein the interlayer is partially included in the cathode, the anode, or both. The present invention can achieve both battery characteristics and safety. R1 to R6 are each one of a hydrogen group (-H), a monovalent hydrocarbon group, a monovalent hydroxyl-group-containing hydrocarbon group, a monovalent group obtained by bonding one or more monovalent hydrocarbon groups and one or more oxygen bonds (-O-), a monovalent group obtained by bonding one or more monovalent hydroxyl-group-containing hydrocarbon groups and one or more oxygen bonds, and a monovalent group obtained by bonding two or more thereof.
