| 摘要 | [Object]There is provided a porous sintered body has a uniform porosity, a high level of freedom in body formation which allows formation into varieties shapes and various levels of porosity, and a very large surface area.[Solution]The porous sintered body includes: hollow cores which follow a vanished shape of an interlaced or otherwise structured fibriform vanisher material; sintered walls 226 which extend longitudinally of the cores and obtained by sintering a first sintering powder held around the cores; and voids formed between the sintered walls. The cores and the voids communicate with each other via absent regions formed in the sintered walls. The sintered walls have surfaces formed with a sintered microparticulate layer 232 made from a material containing a second sintering powder which has a smaller diamater than the first sintering powder, and has predetermined pores 231. | ||||||
