This paper, based on the stochastic frontier approach (SFA), measures the technical efficiency (TE) of Iranian manufacturing industries under the estimation of Translog production function used by the maximum likelihood technique. The findings indicated that out of 140 evaluated industries in this study, 5 industries including the refined primary copper products, cleaning and grading, packing pistachios, manufacture of motor vehicles, manufacture of plastics in primary forms and  manufacture of plastics in primary forms, and of synthetic rubber have had the highest efficiency in 2009. The results also demonstrated that 4 industries; manufacture of food and beverages,  manufacture of tobacco, manufacture of plastic except the footwear, and finally, Manufacture of lifting and handling equipment have experienced the greatest change for efficiency during the period 1995-2009 among the industries.
