A first group of heating filaments is printed on a main section of a wrap-around type rear windowscreen and second and third groups of heating filaments each having a reduced width are printed on side sections of the rear windowscreen between which the main section is interposed. The second and third groups of heating filaments are integrally connected, in one to one relation, to the first group of heating filaments at ridges of the windowscreen by which ridges the main section and the side sections are bound respectively. First highly conductive strips to which the second and third groups of heating filaments are terminated are respectively printed on the side sections. Second highly conductive strips are printed on the ridges to extend along the same while crossing the connecting parts of the first and second, and the first and third groups of heating filaments to connect the same. Third highly conductive strips are printed on the side sections to connect the top ends of the first and second highly conductive strips and to connect the bottom ends of the first and second highly conductive strips. |
