The phenomenon of superconvergence is studied on averaged gradients of the approximate solution. The averaged gradients of the approximate solution are calculated by means of the finite element method with linear elements on triangles with right angles. Local convergence of the averaged gradients in \(L_ 2\) with the rate \(O(h^ 2| \ln h|)\) is proved.
