Abstract: A composite structure comprising two polytetrafluoroethylene porous layers and a framework structural member having a plurality of gaps or openings, the framework structural member being disposed between the two polytetrafluoroethylene porous layers, wherein the composite structure is structured such that the polytetrafluoroethylene porous layers are united together by being adhered with each other through the gaps or openings of the framework structural member and such that the respective polytetrafluoroethylene porous layers (A1) and (A2) are united with the framework structural member closely along the surfaces of the respective constituent elements of the framework structural member in such a manner as to wrap the respective elements. The method of manufacturing the composite structure is characterized in that it includes a step of applying pressure through a mass of fine particles.

Abstract: An object of the present invention is to provide a method for manufacturing a porous material in which complicated and fine through portions, recessed portions, and the like have been patterned. It is to provide a patterned porous molded product or nonwoven fabric, in which a plated layer has been selectively formed on the surfaces of the through portions and the recessed portions. With the invention, a mask having through portions in a pattern is placed on at least one side of the porous molded product or the nonwoven fabric. A fluid or a fluid containing abrasive grains is sprayed from above the mask, thereby to form through portions or recessed portions, or both of them, to which the opening shape of each through portion of the mask has been transferred, in the porous molded product or the nonwoven fabric. The invention provides a porous molded product or a nonwoven fabric in which a plated layer has been selectively formed on the surfaces of the through portions or the recessed portions, or both of these, an electric circuit component, or the like.
