The present invention discloses an atomizer and an electronic cigarettehaving the same, wherein the atomizer present invention comprises a coreassembly. The core assembly defines an air-inlet passage and a smoke-outletpassage at both ends, respectively. At least one atomizing chamberand at least one cooling passage, both of which are communicated with theair-inlet passage and the smoke-outlet passage, respectively, are formed inthe core assembly. The at least one atomizing chamber (103) is spacedfrom the at least one cooling passage (104). The technical solution of thepresent invention solves the problem that the core assembly of the existingelectronic cigarette has a high temperature in use, and improves its usingstability and service life.
