Abstract: An anisotropic conductive sheet which does not damage a wafer nor the electrode terminals of a conduction measuring instrument due to loading when the wafer is to be inspected, and ensures a good conductivity. The anisotropic conductive sheet (1) comprises porous resin layers formed by foaming and electron-beam-crosslinking fluororubber or tetrafluoroethylene-propylene copolymer rubber having an open cell structure and provided on the inner walls of a plurality of through holes (3) pierced in the thickness direction of an electrically-insulating porous sheet (2) made of foamed fluororubber or the like, characterized in that the skeleton surface of the porous resin is coated with metal. In addition, it is especially preferable for porous resin.

Abstract: A method of manufacturing a drilled porous resin base material with conductive drilled inner wall surfaces, comprising a step 1 for penetrating liquid or solution into the porous structure of the porous resin base material, a step 2 for forming solid matter from the penetrated liquid or solution, a step 3 for forming a plurality of drilled holes passed from the first surface to the second surface of the porous resin base material having the solid matter in the porous structure, and a step 4 for melting or dissolving the solid matter and removing it from the porous structure. The method also comprises the step for selectively adhering catalysts to only the inner wall surfaces of the drilled holes and adhering a conductive metal to the inner wall surfaces.
