The problem of plane wave diffraction by an imperfectly conducting wedge BOA with curved convex faces OA and OB is treated and the short-wave asymptotic of the scattered field applicable in the vicinities of faces and near the tangents OA' and OB' to the faces is found. We show that the creeping waves are excited in these domains. In the main term of the asymptotics these waves coincides with the waves excited by a source at a smooth convex surface multiplied by a constant factor which is found in the paper.
