Leaky cable and method of manufacturing leaky cable

A leaky cable having a structure configured to propagate electromagnetic waves, comprising:

• a linear insulator;
• and
• a metal layer formed on an outer peripheral surface of the insulator,
• wherein a slot for leaking the electromagnetic waves is formed through the metal layer between an inner peripheral surface and an outer peripheral surface of the metal layer,
• wherein the outer peripheral surface of the insulator is formed with unevenness that inhibits misalignment of the slot with respect to the insulator,
• wherein a portion of the insulator protrudes from the inner peripheral surface toward the outer peripheral surface of the metal layer at a peripheral edge of the slot,
• wherein the portion of the insulator that protrudes adheres at least a part of the end surface of the metal layer at the peripheral edge of the slot,
• wherein a ratio of a thickness of the metal layer to a radial thickness of the insulator is between 0.2% and 40%, and
• wherein the cable is configured to be bent to 90° without cracking or delaminating the metal layer at a bending radius of 2.5 times an outer diameter of the leaky cable.
