This invention provides a technology allowing a heat generating sheet of an aerosol inhaler used for atomization of aerosol generating liquid to have a sufficient resistance value required as a heater used for the aerosol inhaler, and reduce localization of heat generation of the heater. A cartridge for aerosol inhaler includes a liquid reservoir for storing an aerosol generating liquid, and a heat generating sheet which is provided with a positive electrode and a negative electrode, and generates heat when energized between the positive electrode and the negative electrode to atomize the aerosol generating liquid supplied from the liquid reservoir, the heat generating sheet being formed of a porous material, and slits are provided so as to form a serpentine-shaped circuit portion that is formed into serpentine-shaped, while suppressing localization of current density of a current flowing between the positive electrode and the negative electrode.本發明提供下述技術:在用於氣霧劑產生液的霧化之氣霧劑吸嚐器的發熱片中,具備用於氣霧劑吸嚐器之加熱器所需要的充分的電阻值,且減低加熱器的局部的發熱。氣霧劑吸嚐器用筒匣具備有:儲存氣霧劑產生液之儲液部;以及發熱片,係設有正極及負極,在對正極及負極間通電之際會發熱從而使從儲液部供給的氣霧劑產生液霧化;發熱片由多孔質材料所形成,且設有切縫以抑制流動於正極與前述負極間之電流的電流密度的局部化,而且形成呈蛇形形狀的蛇形形狀電路部。7‧‧‧多孔質發熱片7c‧‧‧上邊7d‧‧‧下邊8‧‧‧切縫8A‧‧‧第一切縫8B‧‧‧第二切縫9A‧‧‧正極9B‧‧‧負極10‧‧‧電路11‧‧‧蛇形形狀電路部11a‧‧‧一端11b‧‧‧另一端12‧‧‧正極設置電路部13‧‧‧負極設置電路部71‧‧‧加熱器部71a‧‧‧第一端緣71b‧‧‧第二端緣110‧‧‧直線電路部120‧‧‧折返電路部
