A method of manufacturing a bumper for impact absorption and a bumper for the impact absorption manufactured from the same are provided. The method includes: filling solid salts in a mold, injecting a molten metal into the mold, and solidifying the molten metal with the solid salts to obtain a solidified product, spraying water onto the solidified product to dissolve the solid salts, which results in obtaining a porous metal having pores, disposing the porous metal in an injection mold, and injecting-inserting a resin composite into the injection mold to surround the porous metal while filling at least a part of the pores in the porous metal.
