세라믹 흡습체(110)가 보유하는 미세기공의 직경은 1 ㎛ 내지 100 ㎛인 것이 액상 형태의 에어로졸 형성 기재를 잘 흡수할 수 있어 바람직하다. 또한 세라믹 흡습체(110)의 기공률은 30 % 내지 70 %인 것이 바람직하다.It is preferable that the micropores of the ceramic moisture absorber 110 have a diameter of 1 ㎛ to 100 ㎛ because they can well absorb liquid aerosol-forming substrates. Additionally, the porosity of the ceramic moisture absorber 110 is preferably 30% to 70%.
실시예에서 열선(120)과 접속 패드(130)는 세라믹 흡습체(110)의 표면 또는 표면 인근에 형성되며, 특히 바람직하게는 금속 프린팅으로 형성된다. 즉, 금속 재질의 잉크를 사용하여 세라믹 흡습체(110)의 표면에 열선 패턴 또는 패드 패턴을 인쇄하여, 일단 소결 후에는 가공이 어려운 세라믹 흡습체(110)의 표면에 복잡한 형태의 열선(120)과 접속 패드(130)를 빠르게 형성할 수 있다. 열선(120)과 접속 패드(130)는 동일한 재질로 형성될 수 있으며, 예를 들어, Ni, Cr, Ti, Cu, Fe, Mo, 그래핀, 칸탈 중 어느 하나일 수 있다. 또는 상기의 예시적인 재질로 열선(120)을 형성하고, 접속 패드(130)는 열선(120)의 재질보다 전기 전도성이 높은 금속 재질로 형성할 수도 있다. 열선(120)은 전기가 흐르며 발열하여, 액상 형태로 세라믹 흡습체(110)에 흡수된 에어로졸 형성 기재를 가열하여 에어로졸을 발생시킬 수 있다. 접속 패드(130)는 열선(120)과 전기적으로 연결되도록 형성되어 배터리(미도시)로부터 전력을 열선(120)에 공급한다.In the embodiment, the heating wire 120 and the connection pad 130 are formed on or near the surface of the ceramic moisture absorber 110, and are particularly preferably formed by metal printing.

Since the connection pad 130 is smaller than the heating wire 120 and has a simple shape, it can be formed by insert sintering. Additionally, depending on the embodiment, the connection pad 130 may be formed through a metal printing process on a surface formed of either a PI film or stainless steel, in addition to the surface of the ceramic moisture absorber 110.
