POROUS SINTERED BODY AND PROCESS FOR PRODUCING POROUS SINTERED BODY

[Object] [0002] The present invention provides a porous sintered body which has a uniform porosity, a high level of freedom in forming, allowing to be formed into varieties of shapes and various levels of porosity, and to be formed to an extremely high level of porosity. [0003] [Means for Solution] [0004] There is provided a porous sintered body 1 which is obtained by sintering a powder 4, and includes hollow cores 5 following a vanished shape of an interlaced or otherwise structured fibriform vanisher material 2; sintered walls 6 obtained by sintering the powder held around the cores and extending longitudinally of the cores; and voids 7 between the sintered walls.
