Based on Feynman and Hibbs’s idea, we give a mathematically rigorous definition of functional derivatives in Feynman path integral. In this definition, the functionals which belong to Fujiwara’s class, can be differentiated as many times as we want. Furthermore, the Taylor expansion formula and the integration by parts hold with respect to the functional derivatives.
