1. A dielectric material, the dielectric material being a tube structure, and a tube wall of the tube structure being formed by foaming a foam material; and the dielectric material further comprising metal wires, and the metal wires being disposed in a longitudinal direction of the tube structure, being evenly distributed in the tube wall of the tube structure without being in contact with each other,
wherein a contour shape of an outer periphery of a cross section of the tube structure is a circle, a contour shape of an inner periphery of a cross section of the tube structure is a circle, the diameter of the outer periphery is 4 mm to 12 mm, and the diameter of the inner periphery is 0.3 times to 0.7 times the diameter of the outer periphery, and a length of the tube structure does not exceed 20 mm.
