In this paper we present an error bound for cubic spline approximation of conic section curve. We compare it to the error bound proposed by Floater \cite{ACM96_Floater}. The error estimating function proposed in this paper is sharper than Floater's at the mid-point of parameter, which means the overall error bound is sharper than Floater's if the estimating function has the maximum at the mid-point.
Keywords: conic section, spline approximation, cubic Be\'zier curve, error analysis, geometric Hermite interpolation
