PROBLEM TO BE SOLVED: To obtain a light-emitting element material excellent in color purity, good in light emission character, and excellent in stability during repeated use, and a light-emitting element. SOLUTION: This light-emitting element material is a compound represented by general formula (I) L-(A)m (wherein A represents a heterocyclic group formed by condensation of two or more aromatic hetero rings, the heterocyclic group represented by A in (A)m may be the same or different. (m) represents an integer of 2 or larger, and L represents a connecting group.), and the light-emitting element uses this material.
