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), Ar
1
represents an organic group A represented by the following general formula (A-1); Ar
2
represents the organic group A or an organic group B represented by the following general formula (B-1); and Ar
3
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 Ar
1
and Ar
2
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), R
1
and R
2
each represent a hydrogen atom, an alkyl group or an aryl group, and R
1
and R
2
may be bonded to each other to form a hydrocarbon ring; R
3
to R
6
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 R
3
and R
4
may be bonded to each other to forma hydrocarbon ring; and in the case where a or b is 2, adjacent groups of R
3
or adjacent groups of R
4
may be bonded to each other to form a hydrocarbon ring,
in the general formula (B-1), Ar
4
and Ar
5
each represent an arylene group; Ar
6
represents an aryl group; R
7
to R
9
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 R
7
to R
9
may be bonded to each other to forma hydrocarbon ring; and in the case where e, f or g is 2, adjacent groups of R
7
, adjacent groups of R
8
or adjacent groups of R
9
may be bonded to each other to form a hydrocarbon ring,
in the general formula (C-1), Ar
7
represents an aryl group; R
10
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 R
10
may be bonded to each other to form a hydrocarbon ring.
