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
