The present invention is a manufacturing method of an atomization unit for a non-combustion type flavor inhaler, which comprises the following steps: a preparation step, which prepares a liquid holding member and a heater, wherein the heater is formed by a heating wire having a linear shape or a belt shape and connecting a pair of electrodes separating from each other and fixed to a base member, and the heater has a stretchable extensible portion； a pressing step, in which a convex surface formed on the liquid holding member is pressed against the extensible portion of the heater such that the protruding direction of the convex surface is orthogonal to the separating direction of the pair of electrodes, by pushing the convex surface relatively to the extensible portion along the protruding direction of the convex surface, the extensible portion is extended from the original state so as to extend along the convex surface of the liquid holding member； a fixing step, which maintains the extensible portion to the extended state by fixing the convex surface in a state pressed against the extensible portion； by maintaining the extensible portion in the extended state, the extensible portion presses the convex surface by the restoring force of the extensible portion acting in the direction to extend the extensible portion.本發明提供一種非燃燒型香味吸嚐器用的霧化單元的製造方法，其中包括以下步驟：準備步驟，係準備液體保持構件及加熱器，前述加熱器是由將一對在基座構件上分開而固定的電極彼此連接並且具有線狀或帶狀的電熱線所形成的加熱器，且具有可伸縮的伸縮部；壓抵步驟，係將形成在液體保持構件的凸狀面，以該凸狀面的突出方向與一對電極的分開方向正交的方式壓抵在加熱器的伸縮部，使該凸狀面沿著該凸狀面的突出方向相對壓入在伸縮部，藉此使伸縮部從原形狀態成為沿著液體保持構件的凸狀面伸長的伸長狀態；以及固定步驟，係固定成將凸狀面壓抵在伸縮部的狀態，藉此使伸縮部維持在伸長狀態；藉著使伸縮部維持在伸長狀態，伸縮部係藉由作用在使伸縮部長度縮短的方向之該伸縮部的復原力而推壓凸狀面。
