Summary:To provide an igniter for an oxygen fusion cutting lance pipe which does not inhibit rapid ignition.SOLUTION: An igniter 1 for an oxygen fusion cutting lance pipe includes: a base body 10; and an ignition material 20 inserted into an ignition material insertion hole 12 provided in the base body 10. The ignition material 20 includes: an outer peripheral material 21 comprising formed coal and having a through hole 21a to which a tip portion of the oxygen fusion cutting lance pipe can be inserted; a bottom material 22 comprising a material more flame-retardant than formed coal and closing a lower end of the through hole 21a; and a combustion material 23 mainly comprising pulverized coal and inserted into the through hole 21a.SELECTED DRAWING: Figure 2 【課題】着火の迅速性が損なわれにくい酸素溶断ランスパイプの着火器を提供する。【解決手段】酸素溶断ランスパイプの着火器１は、基体１０と、この基体１０に設けられた着火材挿入穴１２に挿入された着火材２０とを備える。着火材２０は、成形炭からなり酸素溶断ランスパイプの先端部分が挿入可能な貫通孔２１ａを有する外周材２１と、成形炭より難燃焼性の材料からなり貫通孔２１ａの下端を塞ぐ底材２２と、粉炭を主体としてなり貫通孔２１ａ内に挿入された燃焼材２３とを含む。【選択図】図２
