The volatile substance evaporation element comprises a rod (1) impregnated with volatile substances and is characterised in that said rod (1) is made of sintered wood. Preferably, the porosity of said rod (1) varies between its core (3) and its surface (2), the porosity of said rod (1) being lower on its surface (2) than in its core (3). It makes it possible to increase the capacity of the core of the evaporation element to act as a receptacle for volatile substances.
