Abstract
Four twisted pairs 115 are forced to be brought into contact with a hollow filler 113 and collectively arranged around the hollow filler 113 so as to deform a contact portion into a concave form. The outer periphery of the four twisted pairs 115 collectively arranged is covered with a jacket 117 to form a data transmission cable 111.
