An object of the present invention is to provide a red light emitting element material with high color purity and a light emitting element using the red light emitting element material. The present invention is a light emitting element material including a compound which is expressed by following general formula (A) and a light emitting element using the compound. In the following general formula (A), at least two of R1, R2, and R3 each independently represents an aryl group or heterocyclic group, and at least one of the R1, R2, and R3 contains a group expressed by following general formula (B). In the general formula (B), R4 represents a heterocyclic group or electron attracting group, R5 represents a hydrogen atom or electron attracting group, R6, R7, and R8 each independently represents a hydrogen atom or substituent, and m represents 0, 1, or 2. However, in a case in which only one group expressed by the general formula (B) is contained in the general formula (A), R4 and R5 are not cyano groups at the same time. When R5 is a hydrogen atom, R4 represents a heterocyclic group which has aromatic rings and is formed from 3 to 7 rings. 1
