The electron spin resonance of Fe^<3+> ion in Sr_2Nb_2O_7 single crystal has been studied in the ferroelectric normal phase. The main ESR Iine is associated with |±1/2> transition of Fe^<3+> ion in one of two distorted NbO_6 octahedra. The angular dependence of the ESR Iine can be fitted with the crystal field parameters obtained from the third-order perturbation: |D|=0.50 cm^<-1> and |E|=2.36×10^<-2> cm^<-1>. The calculation based on the superposition model shows that the sign of D is positive and Fe^<3+> ion sites on near the center of the octahedron rather than the position of Nb ion.
