The coil of platinum wire preferably has a flattened configuration to cover a larger front of the flame. The supporting member made of a wire of a refractory metal or alloy, around which the coil is wound, is preferably coated with a coating layer of a ceramic material, e.g., alumina. A simple but very reliable structure for mounting the igniter member in the fire bowl of the cigarette lighter is described. | |
