The design of multi-channel gas electron multiplier (MGEM) with metallic electrodes is proposed, produced and tested. The electrodes of MGEM are produced from the brass plates with thickness of 1 mm, round openings of 1 mm in diameter and 1.5 mm steps between them. The gap between the electrodes is equal to 3 mm, while the total working area has a diameter of 20 mm. The neon gas fillings of the MWGEM chamber with micro admixtures of N2 and H2O have been tested. The total maximal coefficient of proportional multiplication of electrons in neon with admixture of (H2O+N2)<100 ppm of 30000 is obtained.
