[Problem] To provide a volatilizer which can make an evaporated volatile agent visible as smoke and which can make the smoke rise straight up like incense, without diffusing the smoke in the vicinity of a heating part. [Solution] This volatilizer for volatilizing a volatile agent by heating comprises: a volatile-agent holding body including a core material impregnated with the volatile agent and a device body having a supporting part that supports the volatile-agent holding body, and a heating body through which a current is passed and which heats the volatile agent. The device body has a shape such that when the volatile-agent retaining body is supported by the supporting part: an upper space is defined above the core material of the volatile-agent retaining body, the upper space permitting smoke produced by heating the volatile agent to rise upward a surrounding space is formed so as to surround the core material, the surrounding space being connected to the upper space and a lower space is formed below the core material, the lower space being connected to the surrounding space and having an open side.Linvention vise à créer un évaporateur qui peut rendre visible un agent volatile évaporé comme de la fumée et qui peut faire monter cette fumée à la verticale comme de lencens, sans que la fumée ne se diffuse à proximité dune partie chauffante. A cet effet, lévaporateur selon linvention destiné à faire évaporer un agent volatile en le chauffant comprend un corps contenant lagent volatile et comprenant un matériau central imprégné de lagent volatile, et un corps de dispositif présentant une partie support qui supporte le corps contenant lagent volatile et un corps chauffant qui est traversé par un courant et chauffe lagent volatile. Le corps de dispositif a une forme telle que, lorsque le corps contenant lagent volatile est supporté par la partie support, un espace supérieur est défini au-dessus du matériau central dudit corps contenant lagent volatile, cet espace sup
