PROBLEM TO BE SOLVED: To provide a high-frequency coaxial cable with reduced VSWR and attenuation at high frequency. SOLUTION: The high-frequency coaxial cable is provided with a conductor such as a central conductor and an insulator coated on an outer surface of the conductor. For the insulator, a resin with polyethylene by 55 to 95 weight parts (with its density at 0.93 to 0.96g/cm<SP>3</SP>) of a high-density polyethylene (HDPE) synthesized by a phenoxyimine catalyst or a mid-density polyethylene (MDPE) and low-density polyethylene (LDPE) by 45 to 5 weight parts (with its density at 0.92 to 0.93g/cm<SP>3</SP>) mixed and with 0.02 to 3.0 weight parts of foaming core agent added is used. With this, a high-frequency coaxial cable with satisfactory VSWR and attenuation can be obtained. COPYRIGHT: (C)2004,JPO
