Claim:
1. A coaxial cable, comprising: a central conductor having a diameter equal to or less than AWG48; an electrical insulator formed around a circumference of the central conductor, the electrical insulator comprising an electrical insulating tape having a thickness equal to or less than 30 μm wrapped and overlapped around the circumference of the central conductor, the electrical insulating tape including a plurality of uniformly dispersed voids formed at an equal pitch on one outer circumferential surface, the electrical insulating tape comprising a void containing layer, which is formed with the voids thereon, and a reinforcing layer, which is thermally fused and bonded to the void containing layer; and a shield around the electrical insulator, wherein the void containing layer has a lower relative permittivity, a lower mechanical strength and a larger thickness than the reinforcing layer.
