The present invention relates to an optical fiber for generating heat. Provided in a first aspect of the present invention is an optical fiber for generating heat blocking a laser beam by covering a thermal conductive tube (14) on the outer circumferential surface of a reflection pipe (13) for the laser beam transferred through the optical fiber (11) not to go out, and having a gap between the optical fiber (11) and the reflection pipe (11) expanding a heat generation area formed by the laser beam in total longitudinal direction of the optical fiber with coating (12) peeled off by forming multiple grooves on the side surface of the optical fiber (11) to radiate the side surface of the optical fiber (11) with the laser beam 360 degrees; based on the center axis of the optical fiber (11) with the coating (12) peeled off. |
