The distribution of zeros of the partition function is studied for the two- and three-dimensional Ising spin glasses on the complex field plane.  We estimate the density of zeros on the imaginary axis by an importance-sampling Monte Carlo algorithm, which enables us to sample very rare events.  Our result suggests that the density has an essential singularity at the origin, giving the first evidence for a Griffiths singularity in spin glass systems in equilibrium.
