| 1. A micro coaxial cable, comprising:
an inner conductor;
an insulation layer having foaming cells and formed to surround the inner conductor;
an over-foaming preventing layer formed to surround the insulation layer for the purpose of uniform forming of the foaming
cells;
a metal shield layer formed to surround the over-foaming preventing layer; and
a protective coating layer formed to surround the metal shield layer,
wherein the over-foaming preventing layer has a lower melt temperature than the insulation layer,
wherein the over-foaming preventing layer is made of one or more polymer resins selected from the group consisting of polyethylene,
polypropylene and polyethylene terephthalate,
wherein the insulation layer and the over-foaming preventing layer are formed using co-extrusion or tandem extrusion, and
wherein the micro coaxial cable has a diameter of 1 mm or less.
