Abstract: Disclosed is a method of manufacturing an insulating sheet, comprising: forming at least a groove on a flat sheet; a first cutting step for cutting a side surface of the groove by irradiating a laser beam to a side surface of the sheet; a second cutting step for cutting the insulating sheet to completely separate the groove from the insulating sheet by irradiating a laser beam from above the groove having the side surface cut; a tape attaching step for attaching a tape to an outer surface of the insulating sheet; and a bending step for bending one end portion of the surface of the insulating sheet having the tape attached toward a place where the tape is attached. It is possible to mass-produce the insulating sheets having a three-dimensional shape, regarded as being difficult to manufacture with a mold.
