PROBLEM TO BE SOLVED: To provide a metal porous body of a cross section three-dimensional structure without any flash or sharp jutted parts on the surface, with a number of micro pores arrayed in a micro pitch, and yet with a rigid skeleton structure in spite of its light weight. SOLUTION: The metal porous body 1 has numerous juts 3 formed to protrude alternately in front and back of a metal plate 2. Each jut 3 is formed in a frustum of a pyramid with an area of its upper base 5 (a jutted part) smaller than that of its lower base 6. At the upper base 5 of each jut 3 is formed an opening part 8 punched out in a direction from the upper base 5 to the lower base 6 so that a shape of the upper side opening part become a polygon. Further, when a thickness of the metal porous body 1 is d, and a height of the punched part e, a size of each part is set so as to satisfy: 0.3 < e/d < 0.9. COPYRIGHT: (C)2004,JPO&NCIPI |
