    Abstract: An organic EL device that has a high efficiency and a long service life, an electronic apparatus containing the organic EL device, and a compound capable of providing the organic EL device. The compound is specifically represented by the following general formula (1): wherein in the general formula (1), Ar1 represents an organic group A represented by the following general formula (A-1); Ar2 represents the organic group A or an organic group B represented by the following general formula (B-1); and Ar3 represents the organic group B or an organic group C represented by the following general formula (C-1), provided that in the case where both Ar1 and Ar2 are the organic groups A, the organic groups A may be the same as or different from each other, in the general formula (A-1), R1 and R2 each represent a hydrogen atom, an alkyl group or an aryl group, and R1 and R2 may be bonded to each other to form a hydrocarbon ring; R3 to R6 each represent an alkyl group, a cycloalkyl group or an aryl group; and a, b, c and d each independently represent an integer of from 0 to 2, provided that R3 and R4 may be bonded to each other to forma hydrocarbon ring; and in the case where a or b is 2, adjacent groups of R3 or adjacent groups of R4 may be bonded to each other to form a hydrocarbon ring, in the general formula (B-1), Ar4 and Ar5 each represent an arylene group; Ar6 represents an aryl group; R7 to R9 each represent an alkyl group, a cycloalkyl group or an aryl group; e, f and g each represent an integer of from 0 to 2; and h and i each represent 0 or 1, provided that R7 to R9 may be bonded to each other to forma hydrocarbon ring; and in the case where e, f or g is 2, adjacent groups of R7, adjacent groups of R8 or adjacent groups of R9 may be bonded to each other to form a hydrocarbon ring, in the general formula (C-1), Ar7 represents an aryl group; R10 represents an alkyl group, a cycloalkyl group or an aryl group; and j represents an integer of from 0 to 2, provided that in the case where j is 2, adjacent groups of R10 may be bonded to each other to form a hydrocarbon ring.
