  Behavior of hydrogen in a tensile-deformed Al-9 mass%Mg alloy was investigated by means of hydrogen microprint technique, HMPT, a method to visualize the microscopic location of hydrogen emission from specimen surface as silver particles. Hydrogen emission was observed on some of grain boundaries. The amount of surface relief and the maximum gradient across the grain boundary with hydrogen emission were larger than those without hydrogen emission. Most grain boundaries with hydrogen emission were from 61 to 75 degree to tensile direction and nearly parallel to slip lines. The results suggest that slip deformation parallel to and close to grain boundary plane caused hydrogen transport with moving dislocations to the surface, breakage of the surface oxide film on the grain boundary, and then the emission of the hydrogen atoms.<br>
