摘要： Provided is a differential signal transmission cable, a multi-core cable, and a method of manufacturing a differential signal transmission cable that can suppress an increase in differential-to-common mode conversion quantity. The differential signal transmission cable includes two signal lines, an insulation layer covering a periphery of the two signal lines, and a plating layer covering the insulation layer. Differential-to-common mode conversion quantity of the differential signal transmission cable has a maximum value of −26 dB or less, in a frequency band of 50 GHz or less. In the method of manufacturing a differential signal transmission cable, dry ice blasting is performed on an outer peripheral surface of the insulation layer, and then corona discharge exposure is performed on the outer peripheral surface.

摘要： A crimping terminal includes a crimping part that is compressed to a conductive part of an electric wire, and a buffer layer formed on a surface where the crimping part contacts the conductive part. The buffer layer includes a resin, a plating or a grease and a conductive microscopic particle that is mixed and dispersed therein. The microscopic particle includes a fractal structure including a fine protrusion on a surface of the microscopic particle.
