Abstract
Abstract A planar conductive piece has groups of conductive and insulative lines arranged in mutually crossing directions and formed unistructurally. The individual conductive lines are kept in mutually non-contacting relationship such that the two groups of lines form a planar conductive piece with electrical anisotropy.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
An electrically anisotropic planar conductive piece capable of simultaneously transmitting mutually independent electrical signals through a plurality of mutually parallel paths in a specified direction, said piece comprising a first group of conductive lines arranged substantially in said specified direction, a second group of insulative lines arranged substantially in said specified direction, and a third group of insulative lines crossing said first and second groups of lines, said lines all having a diameter no less than 10 micrometers and less than 0.05 millimeter, said first and second groups of lines being arranged together at linear density of more than 10 lines but less than 200 lines per inch, said conductive lines being kept in mutually non-contacting and electrically insulated relationship so as to form mutually insulated current paths.
Claim 2
Dependent Claim
