The invention relates to a sheet material having metal points (8) and
surfaces (2 and 3) located opposite one another, wherein the sheet
material (1) has through-holes (4) from one surface (2) to
the surface (3) located opposite. Those through-holes (4) are filled
with needle-point-shaped conical pins (5) or through-contacts (6)
of electrically conducting material, whereas the surrounding sheet material in
a preferred embodiment of the invention consists of an insulating plastics material
(7). In a further embodiment of the invention, instead of the insulating
plastics material (7) there are provided needle-shaped pins that are surrounded
by air or some other gaseous medium. The invention further relates to a method
for the production of such a sheet material (1) and to forms of use of the
sheet material (1).
