Abstract: PURPOSE: A metal mesh filter with controlled pore size and a manufacturing method thereof are provided to improve porosity, and to uniformize the size of pores. CONSTITUTION: A metal mesh filter with controlled pore size comprises the following steps: removing foreign substances from the surface of a metal mesh with pores having uniform size; laminating first metal powder with the size bigger than the pores on the metal mesh; laminating second metal powder with the size smaller than the pores on the metal mesh with the first metal powder; heating and pressing the metal mesh with the first and second metal powder; and vacuum depositing the metal mesh.
