The present invention relates to an electronic cigarette, comprising: a suction member capable of being sucked by a user into the mouth； An essence container which is fastened to the suction member and filled with liquid essence； A core member which is connected to the +, - terminal of the heating element and fixes the core, a wick to be exposed to the liquid essence, a heating element wound on a part of the core without being exposed to the liquid essence, and a socket to fix the core. A socket fastening portion which is fastened to the lower end of the core member so as to conduct electricity, and a support member having an intake port for introducing outside air； A battery receiver coupled to a lower end of the support member and applying power to the heating element through a support member； And a battery type battery for 1.5 V accommodated in the battery receiver and replaceable, the electronic cigarette comprising: A connector is further provided between the battery receiver and the support member； And a voltage converter for boosting the input voltage of the battery of 1.5 V to an output voltage of 3 to 4 V and applying the boosted voltage to the heating element is installed in the connector. According to the present invention, since the booster function allows the heating element to be accurately heated, the efficiency of the atomization can be promoted, so that a proper taste of the cigarette can be realized, and the effect of enjoying the friendliness without limitation from the outside can be obtained without a dedicated charger.본 고안은 전자담배에 관한 것으로, 사용자가 입에 대고 빨 수 있는 흡입부재； 상기 흡입부재와 체결되고 액상 에센스가 충전된 에센스용기； 상기 액상 에센스에 노출되는 심지, 상기 액상 에센스에 노출되지 않은 상태로 상기 심지의 일부에 감긴 발열체 및 상기 발열체의 +,-단자와 연결되고 상기 심지를 고정하는 소켓을 포함하는 심지부재； 상기 심지부재의 하단과 체결되어 통전시키는 소켓체결부, 외부 공기를 도입하는 흡입구를 갖는 지지부재； 상기 지지부재의 하단에 체결되고, 지지부재의 내부를 통해 상기 발열체로 전원을 인가하는 배터리수용체； 상기 배터리수용체에 수납되고 교체가능한 1.5V용 건전지 형태의 배터리；를 포함하는 전자담배에 있어서； 상기 배터리수용체와 상기 지지부재 사이에는 연결구가 더 설치되고； 상기 연결구에는 배터리의 입력전압 1.5V를 출력전압 3~4V로 승압
