ABSTRACT:
A probing device for electrically contacting with a plurality of electrodes3, 6aligned on an object1to be tested so as to transfer electrical signal therewith, comprising: a wiring sheet being formed by aligning a plurality of contact electrodes21, 110b, corresponding to each of said electrodes, each being planted with projecting probes20, 110acovered with hard metal films on basis of a conductor thin film41formed on one surface of an insulator sheet22of a polyimide film by etching thereof, while extension wiring23, 110cfor electrically connecting to said each of said contact electrodes being formed on basis of a conductor thin film formed on either said one surface or the other surface opposing thereto of said insulator sheet of the polyimide film; and means for giving contacting pressure for obtaining electrical conduction between said extension wiring and said object to be tested by contacting tips of said projecting contact probe formed onto said each contact electrode through giving pressuring force between said wiring sheet and said object to be tested.
