Abstract. In this paper, we study the instability properties of solutions of a kind of functional differential equations of the fifth order with constant delay. Using the Lyapunov-Krasovskii functional approach, we obtain certain sufficient conditions to guarantee that the zero solution of the equation is unstable.

Keywords: fifth order; functional differential equation; instability; Lyapunov-Krasovskii functional.
