It is pointed out that the position and the width of the peak of π-N elastic scattering in the I=J=3/2 state differ from the mass and the width of Δ(1236) respectively, because of the effect of the "background scattering". By taking account of this effect we obtain the mass 1214 MeV and the width 97 MeV of Δ(1236) resonance from π-N elastic scattering data alone. These values are in good agreement with those obtained in the γ+p and the K^++p reactions. We can thus explain why the mass and the width of Δ(1236) produced in the γ+p and the K^++p reactions are different from the usual values. A brief discussion is made about the relation between our theory and Jackson's theory with the energy dependent width.
