This paper is devoted to studying the superconvergence of streamline diffusion finite element methods for convection-diffusion problems. In [8], under the condition that ε≤ h2 the optimal finite element error estimate was obtained in L2-norm. In the present paper, however, the same error estimate result is gained under the weaker condition that ε≤h.
