PROBLEM TO BE SOLVED: To provide a smoking device which has a high smoking efficiency and which can prevent the smoking agent composition from being ejected to the outside of the smoking device even if the amount of the smoking agent composition filled is increased. A bottomed tubular outer container (10) and a bottomed tubular inner container (20) located inside the outer container (10) are provided, and the smoking agent composition (B) is contained in the inner container (20). As a result, the smoke agent portion 21 is formed, the exothermic substance (A) which is in contact with water and generates heat is contained in the outer container 10, and the heating portion 11 is formed, and the bottom wall 12 of the outer container 10 is formed. In the smoker device in which the water passage opening 16 is formed and smoke is generated, the smoker composition (B) contains a drug and an organic foaming agent, and the smoker part 21 has a thickness of The thickness (t1) is 25 mm or more, and the center (h1) of the bottom wall 22 of the inner container 20 and the position (h2) of the upper end 21a of the smoking agent portion on the side wall 23 of the inner container 20 are after the start of heating. The smoking device 1 in which the time difference (ΔT) until reaching 200° C. is 30 seconds or less.
