That is, the user first evaporates ON / OFF SW25 at any time when he or she wants to produce a drug effect.
When the above operation is performed, the microcapsules 37 are exclusively destroyed by energizing the positive electrode 15 for 3 ms. Along with the destruction of the microcapsules 37, the medicine leaches out and spontaneously evaporates, so that the medicine effect is generated in the surrounding space.
Next, when the user operates the evaporation ON / OFF SW25 for the second time at the time when the residual amount of the chemical due to the natural evaporation is reduced, the microcapsules 37 are destroyed by the 10 ms energization of the positive electrode 15.

The vaporized chemical liquid card 43 has the same structure as that of the third embodiment shown in FIGS. Therefore, as shown in FIG.
The chemical solution holding portion 34 is formed on the surface 32a.
The drug solution holding unit 34 is composed of a microcapsule 37 in which a drug solution 36 is enclosed and a binder 45 which holds the microcapsule 37. On the other hand, a conductive layer 33 is laminated on the back surface 32b of the base material 32, and a resistor layer 44 having the same area as the chemical solution holding portion 34 is formed on the surface of the conductive layer 33.
