A battery rod assembly and an electronic cigarette are provided. The battery rod assembly includes a battery rod assembly body. The battery rod assembly body includes a suction end, a battery for supplying power to an atomizing assembly of the electronic cigarette and an aerosol passage communicating with the suction end. The battery and the aerosol passage are separated from each other inside the battery rod assembly body. Since the battery rod assembly body is provided with a separated and sealed aerosol passage, components inside the battery rod assembly may not be immersed by aerosol generated from atomization, thereby ensuring a long service life of the battery rod assembly. The user is avoided from inhaling the cigarette liquid with the electronic cigarette including the battery rod assembly.
