PROBLEM TO BE SOLVED: To provide a filter for filtration which utilizes a mechanism of cake filtration.SOLUTION: A filter for filtration includes a net-like filter base material having a plurality of through holes, and a plating layer which coats a surface of the filter base material. The plating layer is formed of an assembly of precipitates having a polyhedral shape. An average value of a maximum external dimension of the precipitate is 0.5-10 μm. An average value of a diameter of an inscribed circle of the through hole with the plating layer coated is 1-20 μm. An area of the through holes with the plating layer coated with respect to an area of the filter base material is 0.04-5.00%.SELECTED DRAWING: Figure 1 |
