Conductive layer, manufacturing method of the same, and signal transmission substrate
First Claim
1. A method of manufacturing a conductive layer to be included in a signal transmission substrate for transmitting a signal in accordance with a two-dimensional diffusive signal-transmission technology, the conductive layer having a plurality of low resistance regions and a high resistance region to insulate neighboring ones of the plurality of low resistance regions from each other, the method comprising:
- sewing conductive thread in sheet-like material having an insulating property so as to form one of the plurality of low resistance regions using the conductive thread in the high resistance region formed by the sheet-like material;
moving the conductive thread from an end point of sewing of a previously sewed low resistance region to a start point of sewing of a low resistance region to be sewed subsequently;
repeating the sewing and moving to form the plurality of low resistance regions in the high resistance region; and
forming a plurality of holes in the conductive layer by press working so that an electrical component attached to at least one of the plurality of holes is able to transmit a signal between neighboring ones of the plurality of low resistance regions.
