Abstract
It is an objective of the present invention to provide an aluminum porous body which is formed of a pure aluminum and/or aluminum alloy base material and has excellent sinterability and high dimensional accuracy without employing metal stamping. There is provided an aluminum porous body having a relative density of from 5 to 80% with respect to the theoretical density of pure aluminum, in which the aluminum porous body contains 50 mass % or more of aluminum (Al) and from 0.001 to 5 mass % of at least one selected from chlorine (Cl), sodium (Na), potassium (K), fluorine (F), and barium (Ba). It is preferred that the aluminum porous body further contains from 0.1 to 20 mass % of at least one selected from carbon (C), silicon carbide (SiC), iron (II) oxide (FeO), iron (III) oxide (Fe2O3), and iron (II,III) oxide (Fe3O4).
