A method of producing a sugar solution includes a pretreatment step of treating cellulosic biomass with a treatment agent containing ammonia to obtain an ammonia-treated product, an ammonia-treated sugar solution preparation step of enzymatically saccharifying the ammonia-treated product to obtain an ammonia-treated sugar solution, and a purified sugar solution preparation step of removing coumaramide and/or ferulamide in the ammonia-treated sugar solution by purification to obtain a purified sugar solution having a concentration of coumaramide and/or ferulamide of 10 to 1,100 ppm.

An air injection nozzle has an air injection face with a number of air injection holes arrayed at an interval (Py) in first and second staggered rows. The first row and the second rows are positioned at an interval (Px). The air injection face and the sheet running face confront each other at a distance (L). The air injection holes in the air injection face have a diameter (D). The interval (Px), the interval (Py), the distance (L) and the diameter (D) satisfy Formula (1): 6&#x2266;(L/D)/(Px/Py)&#x2266;9, and Formula (2): 4&#x2266;L/D&#x2266;8. This air injection nozzle is employed as a resin film heat treating apparatus in a tenter oven to be used for manufacturing the resin film.

A film production process having a film tentering step and a recovering step, characterized by detecting the side edge positions of the film running toward the recovering step, transferring the film running direction based on the detected information, and controlling the clamp start position of the film arriving at a tenter in the tentering step by clamp means, in the transverse direction of the film. A film production process having a film tentering step, characterized by controlling the clamp start position of a film arriving at a tenter by clamp means, in the range from 5 mm to 1,000 mm from the tip of the film in the longitudinal direction of the film.
