An electronic cigarette comprises an electronic cigarette body; the electronic cigarette body is provided with a smoking end (1), an oil storage assembly (4) for containing cigarette oil, an atomization assembly (3) for atomizing the cigarette oil and a battery component (2) for powering the atomization assembly (3); the oil storage assembly (4) is arranged on one end of the electronic cigarette body which is in an opposite side of the smoking end (1), since a smoke passage does not pass through the oil storage assembly (4), a user can be effectively prevented from sucking a non-atomized cigarette oil; and meanwhile, through an arrangement of a protective sleeve (5) for containing the oil storage assembly (4) on the electronic cigarette, a vibration-resistance of the oil storage assembly (4) can be enhanced, so that a risk that the oil storage bottle is easily broken is avoided.
