Abstract
A high-quality porous aluminum sintered compact, which can be produced efficiently at a low cost; has an excellent dimensional accuracy with a low shrinkage ratio during sintering; and has sufficient strength, and a method of producing the porous aluminum sintered compact are provided.The porous aluminum sintered compact is the porous aluminum sintered compact (10) that includes aluminum substrates (11) sintered to each other. The junction (15), in which the aluminum substrates (11) are bonded to each other, includes the Ti—Al compound (16) and the Mg oxide (17). It is preferable that the pillar-shaped protrusions projecting toward the outside are formed on outer surfaces of the aluminum substrates (11), and the pillar-shaped protrusions include the junction (15).
