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 N_2 and H_2O have been tested. The total maximal coefficient of proportional multiplication of electrons in neon with admixture of (H_2O+N_2)<100 ppm of 30000 is obtained.
