The invention provides a screen plate for screen printing and a making method thereof. The screen plate comprises a screen frame (1) and screens (2 and 3) bound with the screen frame (1), wherein the screens comprise a first screen (2) and a second screen (3) the mesh number of which is less than that of the first screen, the first screen occupies the all area in the screen frame (1), the second screen (4) is quadrate, is arranged around the first screen and is overlapped with the first screen (2), and at least one bonding line or bonding belt (4) is arranged along the second screen and bonds the first screen and the second screen together. The screen plate for screen printing can maintain the tension stability and the dimensional accuracy for a long time. Compared with a screen plate which comprises only one layer of the same first screen (without the second screen), the screen plate for screen printing provided by the invention is easier and safer to achieve higher tension.
