There is provided a coaxial electric wire and a method for manufacturing the coaxial electric wire able to form a homogenous and stable insulating layer while simplifying a manufacturing apparatus. A coaxial electric wire (1) is provided with an inner conductor (2), an inner insulating layer (3) covering a periphery of the inner conductor (2), an outer conductor (4) covering a periphery of the inner insulating layer (3), and an outer insulating layer (5) covering a periphery of the outer conductor (4). The inner insulating layer (3) is made of a first insulating tube (3A) having an elongated cylindrical shape and an insulation performance. The outer insulating layer (5) is made of a second insulating tube (5A) having an elongated cylindrical shape and an insulation performance. The outer conductor (4) is made of a conductive tube (4A) having an elongated cylindrical shape and conductivity. The coaxial electric wire (1) is manufactured by inserting the inner conductor (2) into the first insulating tube (3A), inserting the first insulating tube (3A) into the conductive tube (4A), and inserting the conductive tube (4A) into the second insulating tube (5A). |
