The invention discloses a film viewer for industrial rubber film inclusion detection; the film viewer comprises a frame, a base plate arranged in the frame and mounted on a frame bottom slot, a plurality of LED tubes with supports and fixed on the base plate, and a light transmission panel arranged on a frame top slot in the frame; the plurality of LED tubes are arranged side by side at even intervals, and are connected in parallel by a three-phase cable; the three-phase cable is connected in series with a switch, and connected with a three-phase plug; the illumination angle [alpha] of each LED tube is 140 to 150 degrees; the distance between the LED tube and the bottom surface of the light transmission panel is the diameter of the LED tube; the illumination intensity passing the industrial rubber film is 280 to 320lx. The film viewer employs a light transmission detection mode, is high in inclusion detection rate, and low in detection cost; the illumination intensity passing the industrial rubber film is con
