Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inexpensive method for efficiently forming the porous aluminum layer only on a required part, and a shock-absorbing member manufactured by the method. SOLUTION: In this method, a porous aluminum layer 31 is formed on a base metal by generating arc 22 by a non-consumable electrode on an aluminum or aluminum alloy base metal 20 by using an AC welding power source 21, and charging aluminum or aluminum alloy powder 14 in the arc. Powder containing hydrogen of 0.5-50 cc/100g is used as a gas generating component. COPYRIGHT: (C)2004,JPO
