## Abstract

A cartridge includes a liquid storage chamber and an atomizing device. The atomizing device includes an atomizing base and a liquid absorbing member installed in the atomizing base. The atomizing base is provided with an atomizing chamber therein. The atomizing base is made of an elastic material. The atomizing base is provided with a through hole. The liquid absorbing member extends through the through hole, and the inner wall of the through hole closely abuts against the outer wall of the liquid absorbing member to isolate the liquid storage chamber from the atomizing chamber. No gap causing e-liquid leakage is present between the liquid absorbing member and the through hole, thereby effectively preventing e-liquid leakage, achieving good isolation between e-liquid and vapor, and simplifying the assembly process. An electronic cigarette having the cartridge is also provided.
