  The possibility of identifying some of Galactic gamma-ray sources as clusters
of primordial black holes is discussed. The known scenarios of supermassive
black hole formation indicate the multiple formation of lower-mass black holes.
Our analysis demonstrates that due to Hawking evaporation the cluster of black
holes with masses about $10^{15}$ g could be observed as a gamma-ray source.
The total mass of typical cluster is $\sim 10 M_\odot$. Detailed calculations
have been performed on the basis of specific model of primordial black hole
formation.
