## Abstract

A smoke generation product and a manufacturing method therefor, which relate to the technical field of tobaccos. The smoke generation product comprises a filter tip base body, a second connecting component, and an aroma generation portion. The filter tip base body comprises a first connecting component, and comprises a cooling portion and a filtering portion that are sequentially disposed in a smoking direction. The filtering portion and the cooling portion are connected by means of the first connecting component. A filtering passage and a cooling passage are in mutual communication. The aroma generation portion is connected to the filter tip base body by means of the second connecting portion, and the aroma generation portion is configured to release smoke by means of heating and make the smoke enter the cooling passage.
