Provided is an organic material which can be employed for manufacturing an organic electroluminescent device having a long luminance half-lifetime. The organic material is a composition containing: a borane compound represented by Formula (B1):
wherein three Ar
B1
represent an arylene group or a divalent aromatic heterocyclic group; and three X
B1
represent an aromatic amino group, a monovalent aromatic heterocyclic group, an alkyl group, or a hydrogen atom; and a conjugated polymer compound represented by Formula (P1):
wherein Ar
p1
represents an arylene group, with the proviso that Ar
p1
is different from Flu
