The specific sum rules in the theory of electrical double layer are formulated as the consequence of contact theorem. They concern the correlation functions of electrolyte when one ion is located on the surface. A simple interpretation of the obtained relations is given.

Key words: electrolyte solution, double layer, contact theorem, sum rules
