To provide a fumigation vaporizer that can be used with a safe and efficient method more than before, by quickly vaporizing and exhausting the fumigant capable of being widely utilized as for agriculture or quarantine inspection owing to insecticide, sterilization and weeding effect with a direct heating system.SOLUTION: A fumigation vaporizer is configured as follows: a bubble plate 130 where many bubble holes 132a are formed to make a row and line is provided so as to be separated from a bottom surface of an internal space part 112 of a fumigation vaporizer body 110 by a predetermined distance； the fumigation vapor comes up by supplying non-explosive gas to the lower space part of the bubble plate 130 and making the gas come up through the bubble holes 132a, and thereby vaporization performance is improved； and the cost by the use of the fumigant can be reduced, and the simplification of a device can be constructed.SELECTED DRAWING: Figure 8【課題】殺虫、殺菌、及び、除草効果によって農業又は検疫用などとして広く活用できる燻蒸剤を直接加熱式で迅速に気化させて排出されるようにして、従来より安全かつ効率的な方法で使用することのできる燻蒸気化器の提供。【解決手段】燻蒸気化器本体１１０の内部空間部１１２の底面から所定の距離だけ離隔されるように多数のバブル孔１３２ａが列と行をなすように形成されたバブル板１３０を設け、バブル板１３０の下部空間部に非爆発性ガスを供給してバブル孔１３２ａを通じて上昇するようにして、燻蒸気化物質を上昇させることにより、気化性能を向上させ、燻蒸剤の使用による費用を減少させることができ、装置の簡素化を構築できる燻蒸気化器。【選択図】図８
