Disclosed are a powder sintered porous metal with better comprehensive properties, especially with good corrosion resistance to hydrofluoric acid, and a filter element using same. The powder sintered porous metal of the present invention has a porosity of 25-60%, an average pore diameter of 0.5-50 μm and a weight loss rate of at most 1% after being immersed into a hydrofluoric acid solution with a mass fraction of 5% at room temperature for 20 days; and the powder sintered metal porous body consists of Cu accounting for 23-40 wt %, Si accounting for 0-5% and the balance of Ni, based on the weight of the powder sintered metal porous body. The powder sintered porous metal of the present invention has good mechanical properties and machinability, and excellent corrosion resistance in acid mediums, especially in hydrofluoric acid mediums. In particular surprisingly, when Cu and Ni are introduced into the powder sintered porous metal by Cu element powders and Ni element powders doped in the raw material powders, the powder sintered porous metal has significantly improved permeability and backflushing regeneration property.
