  • Patent number: 11660556
    Abstract: It is an object of the present invention to provide a filter having excellent filtration rate and excellent permeability and a method for producing the same. To achieve the above object, the present invention provides a filter comprising a porous metal support having the first pore size; and a metal coating layer formed on the support and having the second pore size smaller than the first pore size, wherein the coating layer has a three-dimensional pore structure by bonding flake-shaped metal powders. The present invention also provides a method for producing the filter. According to the present invention, as the flake-shaped second powders form a coating layer, the porosity increases and the permeability increases, and as the flow channel becomes more complicated, the filtration rate also increases.
