The invention discloses coated glass with a top-layer transparent electric-conduction protection film structure. Target material arc light stable sputtering is adopted for a top-layer protection film (1), the voltage fluctuation of the sputtering process is smaller than 1 V, and the sputtering speed is (0.5-1.0) nm*m/min; a coating film layer serves as a protection film and has good wear resistance, and therefore scratching and scraping in the subsequent machining process of the coated glass are effectively prevented. Meanwhile, the coating film layer has good weather resistance, film sticking protection is not needed after the glass is coated with the film, and oxidation of the film layer does not occur when the glass is exposed in air for 30 days. The good bonding force between the coating film layer of a target material and an adjacent film layer is achieved, after the Low-E coated glass is toughened, film disengaging cannot occur, scratches do not exist, the wear resistance and the scratch-preventing performance of the glass coating film layer are improved, and the scrap rate of the coated glass in the deep processing process is obviously reduced; the wear resistance of the coated glass is improved, the coated glass passes through a salt spray test of 600 hours and is not oxidized after being toughened at a high temperature, and the stable decoration performance and optical performance of the coated glass are ensured.
