To provide a lid of a smoking device in which the fine powder leakage of a smoking agent in the transportation and the ejection of the smoking agent in the heating can be prevented together by a simple structure, and provide an indirect heating type smoking device and a direct heating type smoking device using the lid.SOLUTION: A lid 1 of a smoking device includes a circular sealing material 20 comprising a heat melting film overlapped to a top plate part 11 so as to cover a smoking hole 15 of the top plate part 11. In the sealing material 20, respective multiple slits 21, 22 are formed in the inside and outside of a concentric circle R2 with a radius being a half of the radius of the sealing material. A portion or all of the slits 21, 22 are partially overlapped with the smoking hole 15 formed to the top plate part 11. Also, there are provided an indirect heating type smoking device and a direct heating type smoking device using this lid 1.SELECTED DRAWING: Figure 1【課題】簡単な構造で、輸送時等における燻煙剤の微粉漏れと加熱時の燻煙剤の噴出を共に防止できる燻煙装置の蓋体と、この蓋体を用いた間接加熱型燻煙装置、及び直接加熱型燻煙装置を提供する。【解決手段】天板部１１の通煙孔１５を覆うように、天板部１１に重ねられた熱溶融性フィルムからなる円形のシール材２０を備え、シール材２０には、半径がシール材の半径の１／２である同心円Ｒ２の内側と外側に、各々複数のスリット２１、２２が形成され、スリット２１、２２の一部又は全部は、天板部１１に形成された通煙孔１５と部分的に重なる燻煙装置の蓋体１、及びこの蓋体１を用いた間接加熱型燻煙装置と直接加熱型燻煙装置。【選択図】図１
