An objective of this invention is to provide a cartridge for inhaler having a novel structure and an inhaler. This invention provides a cartridge for inhaler. The cartridge includes a housing having a receiving space capable of receiving liquid, an air flow path and a partitioning member for partitioning the receiving space and the air flow path along a longitudinal direction, a heater configured to enable heating of the liquid and disposed in the air flow path, and an air inlet provided at a position opposing to the partitioning member and communicating with the air flow path. The housing has an air outlet communicating with the air flow path, wherein the position of the air outlet in a lateral direction and the position of the heater in the lateral direction are at least partially overlap with each other as viewed from the longitudinal direction, or an end of the air outlet near to the air inlet side in the lateral direction is nearer to the receiving space side than an end of the heater near to the air inlet side in the lateral direction.本發明之目的在於提供一種具有新構造之吸嚐器用筒匣及吸嚐器。本發明係提供吸嚐器用筒匣。該筒匣係包含:具有可收容液體的收容空間、空氣流路、及沿長邊方向區隔收容空間與空氣流路的區隔構件之外殼;構成為可加熱液體,且配置在空氣流路內之加熱器;以及設在與區隔構件相對向的位置,與空氣流路連通之空氣流入口。外殼係具有與空氣流路連通之空氣流出口,從長邊方向觀看時,短邊方向之空氣流出口的位置與短邊方向之加熱器的位置係至少部分重疊,或者,短邊方向中之空氣流出口之靠近空氣流入口側的端部,相較於短邊方向中之加熱器之靠近空氣流入口側的端部,係位於收容空間側。31a‧‧‧收容空間32‧‧‧供液口34‧‧‧空氣流出口36‧‧‧區隔構件40‧‧‧液體保持構件50‧‧‧加熱器60‧‧‧遮罩構件62‧‧‧空氣流路、內部空間
