The tunnel current of Al tunnel junctions (Al-Al_2O_3-Al) has been first measured up to ±1200 mV at 4. 2K. It has been found that the current had the rectification property and was approximately proportional to V, V^2 and V^3. The experimental results are in good agreement with the numerical calculations introducing the bias dependence of the effective mass to the WKB approximation with trapezoidal potential. The potential values used in the calculations are consistent with the expected values from the photoemission measurement. The experimental data are also compared with the numerical calculations by the WKB approximation without the bias dependence of the effective mass and the two-band model.
