< Topic >Until it ignites in the incense stick flux, as time is compacted, the incense stick flux which is ignited lifting the flame at a stroke, the core and its incense stick structure which for the incense stick is not a possibility of burning are offered.SolutionsTo install in incense stick flux 2, core 1 for possible incense stick ignition, coat doing the surface of the twist yarn at wax amount, because it made interposition possible from one end side of incense stick flux 2 by making the said twist yarn solidify, until it ignites in incense stick flux 2, as it compacts time, the incense stick flux 2 which it ignites lifting the flame at a stroke, there is no possibility of burning.< Choice figure >Drawing 2【課題】線香束に着火するまでの時間を短縮するとともに、着火した線香束が一気に炎を上げて燃えてしまうおそれがない線香用芯及びその線香構造を提供する。【解決手段】線香束2に取り付け可能な線香着火用芯1であって、撚糸の表面を蝋分でコーティングして該撚糸を固化させることにより、線香束2の一端側から挿入可能としたので、線香束2に着火するまでの時間を短縮するとともに、着火した線香束2が一気に炎を上げて燃えてしまうおそれがなくなる。【選択図】図2
