To provide a coaxial cable which enables bending and is excellent in impact resistance.

A coaxial cable comprises: an internal electric wire; a first insulation layer disposed at the outer peripheral side of the internal electric wire; a pipe like electric wire disposed at the outer peripheral side of the first insulation layer; a second insulation layer disposed at the outer peripheral side of the pipe like electric wire; and a protection pipe disposed at the outer peripheral side of the second insulation layer. A gap part is formed in at least one of a space between the internal electric wire and the first insulation layer, a space between the first insulation layer and the pipe like electric wire, a space between the pipe like electric wire and the second insulation layer, and a space between the second insulation layer and the protection pipe.
