We calculate the primordial black hole abundance in the context of a Wess-Zumino type no-scale supergravity model. We modify the Kähler potential, by adding an extra exponential term. Using just one parameter in the context of this model, we are able to satisfy the Planck cosmological constraints for the spectral index ns , the tensor-to-scalar ratio r, and to produce up to ~ 20 % of the dark matter of the Universe in the form of primordial black holes.
