Zusammenfassung:	To provide an igniter for an oxygen fusion cutting lance pipe including a substrate that is less likely to be broken even when the number of ignition works is repeated, suppressing thermal conduction and having excellent safety.SOLUTION: An igniter 1 includes: a substrate 10 made of a wooden material; a base material 20 installed at a bottom surface of a cylindrical body fitting hole 12 bored in the substrate; a cylindrical body 30 installed on the base material; and a combustion material 43 inserted into the cylindrical body. The base material 20 and the cylindrical body 30 are made of a material having fire-retardant property that is higher than that of a wooden material. The base material 20 holds and fixes a lower end part of the cylindrical body 30 so as to cause a space W to be generated between an outer peripheral surface of the cylindrical body 30 and an inner peripheral surface of the cylindrical body fitting hole 12.SELECTED DRAWING: Figure 2 【課題】着火作業の回数を重ねても基体が損傷にくく、しかも熱伝導を抑え安全性に優れた酸素溶断ランスパイプの着火器を提供する。【解決手段】木材からなる基体１０と、この基体に設けられた筒体装着穴１２の底面に設置されたベース材２０と、このベース材の上に設置された筒体３０と、この筒体内に挿入された燃焼材４３とを備える着火器１である。ベース材２０及び筒体３０は木材より難燃焼性の材料からなり、ベース材２０は、筒体３０の外周面と筒体装着穴１２の内周面との間に隙間Ｗが生じるように、筒体３０の下端部を保持又は固定している。【選択図】図２
