We study the superconducting transition near the half-filling of electron-doped cuprates with the so-called T'-structure based on an effective two-band model using uctuation-exchange approximation and solving the linearized Eliashberg equation. We find d-wave superconductivity even at the half-filling of this model when the energy difference between the upper Hubbard level of Cu dx2-y2 orbitals and O 2p levels is less than about 1.5eV, which is plausible for the T'-type cuprates.
