Abstract：In this paper， a class of nonlinear Volterra-Fredholm type sum difference inequalities is studied. We make use of the common processing methods of analytical mathematics， such as inequality contraction， inverse functions， substitution of variables， summation and monotony techniques. In this paper， the explicit upper bound estimation of unknown function and difference inequality is derived， which generalizes the existing conclusions in the literature， and illustrates the correctness of the explicit upper bound estimation of unknown function with examples.
