Abstract
Fine powder particles of an electrically conductive or semiconductive material, which have a diameter of 10 .mu.m or less, are pressurized, and at the same time, a pulse voltage is applied between the fine powder particles to produce an electric discharge therebetween. The fine powder particles are fused together at areas where they contact each other, thereby producing a porous sintered body. The porous sintered body is made of only an electrically conductive or semiconductive material without using any particle binders whatsoever.
