Claim:
1. A composite cable mounted in an industrial robot, comprising: a center member for feeding towards an end effector of the industrial robot, during operation of the industrial robot, a fluid or welding wire material used by the end effector for a work of the industrial robot; a first signal line arranged at an outer circumferential side of the center member, and connected to an encoder or Hall element built in a servo motor which drives the industrial robot, the first signal line being configured to transmit a first signal from the encoder or the Hall element; a shield which surrounds the first signal line and blocks an electromagnetic wave; a second signal line arranged at an outer circumferential side of the shield, and connected to the end effector, the second signal line being configured to transmit a second signal different from the first signal; a power line arranged at an outer circumferential side of the second signal line; a partition member of paper material arranged between the second signal line and the power line so as to surround the second signal line, the partition member being configured to divide the second signal line and the power line into different layers; and a tubular sheath which surrounds the power line, wherein the composite cable is configured so that an electromagnetic wave propagated from the outside of the composite cable toward inside of the composite cable reaches the shield and is blocked by the shield.
