Heat-resistant coaxial cable and heat-resistant coaxial cable with connector

Abstract

To provide: a heat-resistant coaxial cable which can enhance heat-resistant characteristics while suppressing lowering of electric characteristics; and a heat-resistant coaxial cable with a connector which is provided with the heat-resistant coaxial cable and a connector.SOLUTION: A heat-resistant coaxial cable 3 includes: an internal conductor 4; an insulator 5 arranged on an outer periphery of the internal conductor 4; a heat-resistant tape layer 6 which is spirally wound around an outer peripheral surface 5a of the insulator 5 and is composed of a heat-resistant tape 61; and a tubular external conductor 7 arranged on an outer periphery of the heat-resistant tape layer 6. The external conductor 7 has such air tightness as to prevent gas therein from being leaked to the outside. The heat-resistant tape 61 is wrap-wound so that ends in a width direction are overlapped with each other, and a width W2 of a lap part 602 where the ends of the heat-resistant tape 61 are overlapped with each other is 2 mm or more, and is less than a half of a width W1 of the heat-resistant tape 61.SELECTED DRAWING: Figure 1
