An anisotropic conductivity sheet ( 10 ) comprising an insulating sheet ( 11 ) having a number of through-holes ( 12 ) and a number of conductive bodies is provided. The insulating sheet ( 11 ) has an inner layer ( 11 A) of a heat resistant fuloro-elastomer and surface thin layers ( 11 B, 11 C) of heat-resistant engineering plastics. Each of the conductive bodies is a wire loop ( 13 ) formed to generally elliptic shape. They are arranged within each of the through-holes ( 12 ) so that long axis of each wire loop ( 13 ) extends in the thickness direction of the insulating sheet ( 11 ). The anisotropic conductivity sheet ( 10 ) is suitable to use for electrical test of a semiconductor devise ( 16 ), such as IC. A signal waveform-rectifying sheet ( 20 ) is preferably arranged on the anisotropic conductivity sheet ( 10 ). The signal waveform-rectifying sheet ( 20 ) has though-holes ( 22 ) in which electrical components for rectifying signals and currents, such as resistors ( 23 A), LEDs ( 23 B), LR circuits ( 23 C) and capacitors ( 23 D), are filled up.
