An micro coaxial cable is disclosed, which includes: a center conductor (3) that enables transfer of a signal; an insulator (5) that covers a periphery of the center conductor (3); an external conductor (8) as a shield that covers a periphery of the insulator (5); and a jacket (8) that covers a periphery of the external conductor (8), in which the insulator (5) is formed of a resin composition containing insulating resin, carbon black and fired pigment, and the fired pigment contains titanium (Ti), antimony (Sb) and chromium (Cr). In accordance with the present invention, such an micro coaxial cable is provided, which does not damage the insulator or the center conductor at the time of processing a terminal end of the micro coaxial cable concerned by using a laser beam.
