A C-type electric pole support having two end lifting parts under-bracing is provided to increase grounding force between the pole and the soil, and to reduce the weight of the electric pole support by forming bolt coupling holes at two sides of the hook insertion holes separately. A C-type electric pole support(10) includes two end lifting parts(11,11'), an outer diameter reduced part(12), a hook insertion hole(13), and slit type bolt holes(14,14'). The two end lifting parts are formed at two upper ends of the pole. The outer diameter reduced part with a smaller outer diameter is formed at the rear side of the electric pole support. The hook insertion hole is formed at the center of the electric pole support. The slit type bolt holes are formed at both sides of the hook insertion holes. A first friction increasing groove(15) is formed at the end of the hook insertion hole of the outer diameter reduced part. Second friction increasing grooves(16,16') are formed at the ends of the bolt insertion holes of the outer diameter reduced part.
