To provide an electroluminescent element which takes color to a wavelength of blue color part to blue green color part, excels in color taking characteristic and light emitting luminance, and excels in the durability so that a dark spot is not observed visually by containing at least one compound containing at least one unit having a specific structure.

This electroluminescent element contains at least one compound containing at least one unit expressed by the formula (where, X1 denotes an oxygen atom, a sulfur atom or > NR6 group, R1 denotes an aromatic group or an alkenyl group, each of R2 to R6 denotes a hydrogen atom or a substituent, at least one of R2 to R5 denotes an aromatic group, and each of Ra and Rb denotes a hydrogen atom or a substituent). In this case, it contains at least one high molecular weight compound in which R3 is an aromatic group, Ra and Rb are each hydrogen atom, R4 is an aromatic group, R1 is an aryl group, an aromatic group present in R2 to R5 is an aryl group and which has a skeleton expressed by the equation in a main chain.
