ABSTRACT:
A method for manufacturing a fine porous member provides that vacant space within the porous member is sufficiently finely small such that the thermal conductivity of the member is lower than that of stationary air. In the method, a fine particle powder together with an ultrafine particle powder preliminarily subjected to a surface treatment for prevention of cohesiveness and employed at least as a part of the fine particle powder, are molded into the fine porous member, whereby the vacant space between the respective particles are made finely small to a remarkable extent and the porous member is provided as highly adapted to be used as a heat insulator.
