We present a new EROS-2 measurement of the microlensing optical depth toward the Galactic Bulge .
Light curves of 5.6 \times 10 ^ { 6 } clump-giant stars distributed over 66 deg ^ { 2 } of the Bulge were monitored during seven Bulge seasons .
120 events were found with apparent amplifications greater than 1.6 and Einstein radius crossing times in the range 5 { d } < t _ { E } < 400 { d } .
This is the largest existing sample of clump-giant events and the first to include northern Galactic fields .
In the Galactic latitude range 1.4 \degr < |b| < 7.0 \degr , we find \tau / 10 ^ { -6 } = ( 1.62 \pm 0.23 ) \exp [ - a ( |b| -3 { deg } ) ] with a = ( 0.43 \pm 0.16 ) deg ^ { -1 } .
These results are in good agreement with our previous measurement , with recent measurements of the MACHO and OGLE-II groups , and with predictions of Bulge models .
