Abstract
A shaped body is molded from fine particles such as powder, whiskers and short fibers, by preparing a slurry consisting of the fine particles and a supercritical fluid containing a small amount of binder dissolved therein, and supplying the slurry into a mold cavity through an inlet port, so that the fine particles suspended in the supercritical fluid are stacked in the cavity to form a layer as the supercritical fluid is exhausted out of the mold cavity through an outlet port.
