To provide a radiation noise suppressing device capable of fully suppressing radiation noise from an electric cable which is connected to a digital type electronic equipment.
An electrical cable 2 is covered with a cylindrical magnetic substance 3, capable of realizing a magnetic shield function with respect to an electric cable 2, a cylindrical conductive body 4 having a static shield function is arranged at the outer side of the magnetic substance 3, only one end portion 4a close to an electronic equipment PC of the cylindrical conductor 4 is connected to the ground of the electronic equipment PC, the other end 4b is not connected to the ground in configuration, and the radiation noise of the electric cable 2 is adequately suppressed through absorbing of the radiation noise by the cylindrical conductive body 4, which otherwise cannotr be fully absorbed by the cylindrical conductive body 4 alone. Also, by the use of a cylindrical case functioning as a conductive body and realizing static shield function, a long-side case is installed and an arrangement of an electrical conductor can be realized.
