Abstract: A high voltage testing device for testing a coaxial cable including a central conductor and a shield conductor surround a periphery of the central conductor with an insulating material and applying a high voltage between the central conductor and the shield conductor of the coaxial cable, includes a cable connecting part that respectively connects two electrodes of an output of a tester which outputs a high voltage to the central conductor and the shield conductor of the coaxial cable. The cable connecting part includes a core wire short-circuiting part which electrically short-circuits between one end and the other end in the longitudinal direction of the central conductor of the coaxial cable and a shield wire short-circuiting part which electrically short-circuits between one end and the other end in the longitudinal direction of the shield conductor of the coaxial cable.

Abstract: There is provided a noise eliminating wire harness capable of enhancing a noise elimination performance. In the wire harness 31, an intermediate portion of a sheath 34 of a wire 33 is removed to expose a conductor 35, thereby forming a conductor connection portion 36, and a capacitor 39 is directly connected to this conductor connection portion 36. The capacitor 39 is directly connected to the conductor connection portion 36 without using any wire serving as a branch wire. The capacitor 39 is connected to the conductor connection portion 36 in perpendicularly intersecting relation thereto. The capacitor 39 is connected to the wire 33 in such a condition that there is not provided any portion extending side by side with the wire 33.
