The invention relates to a disposable, active substance-releasing electrical device. The inventive device comprises a container (1) for the active substance in liquid form and a permeable membrane (3) which is used to seal said container and which allows the passage of the active substance vapour, but prevents the passage of liquid. The invention also comprises a porous support (5) which is disposed on the inner face of the aforementioned membrane (3) in order to convey the active substance towards the centre of the membrane (3). According to the invention, the substance is heated by a heating element (9) comprising pins (10) which are directly connected to the pins (8) of a plug (7), by means of which the device is powered. In this way, the heating of the active substance causes same to evaporate and leave the device through windows (12) which are provided in the structure (11) used to connect the container (1) to the plug (7). The above-mentioned assembly forms a disposable device, although the container (1) can be produced such as to be interchangeable.
