PROBLEM TO BE SOLVED: To provide a four-pair LAN cable capable of high-speed data communication by always keeping the distance between the four insulated conductors having twisted pair wires and also having a function for an optical LAN cable as the case may be. SOLUTION: This four-pair LAN cable is composed by disposing an object 12 at the center, and by circularly arranging the four insulated conductors 14 each having a metal twisted pair wire 20 and having the same diameter larger than that of the object 12 around it so as not to form gaps between them.
