The oligoaniline compound having the triphenylamine structure represented by the formula (1) can exhibit good luminescence efficiency and luminance characteristics even when used in either an OLED device or a PLED device, and has good solubility in an organic solvent. Therefore, it is applicable to various coating methods.n n n (Formula 1)n n n n n n n n (R 1 and R 2 each independently represent a hydrogen atom, a substituted or unsubstituted monovalent hydrocarbon group, t-butoxycarbonyl group, and the like, and R 3 to R 34 each independently represent a hydrogen atom, a hydroxyl group, or a silane).
