In order to maintain the smoothness of the overall shape of the atomizer, the first housing 11 substantially covers one main surface and two side surfaces of the second housing 12, and the first housing 11 is engaged with the outer periphery of the other main surface of the second housing 12 in an arc transition according to the profile of the side edge of the other main surface of the second housing 12.

Also provided inside the second housing 12 are an atomizing core assembly 24 and a sleeve 23 for fixing the atomizing core assembly 24. Atomizing core assembly 24 includes heating element 22 and liquid-conducting element 21, and at least a portion of liquid-conducting element 21 is capable of absorbing the liquid matrix inside reservoir chamber 14 while at least a portion of liquid-conducting element 21 is in contact with heating element 22, thereby supplying the liquid matrix inside reservoir chamber 14 to heating element 22 for atomization.
