題を有していた。The atomizing pump nozzle lip (hereinafter referred to as a unit part) configured in this manner was joined to a support body 6 made of metal, and lead wires 7a and 7b were connected thereto. Note that in the figure, number 8 is a liquid passage, and number 9 is a liquid chamber. In this configuration, since the electrical vibrator 1 (including one negative electrode film 2b) and the nozzle plate 3 are bonded by the adhesive layer 5, the negative electrode film 2b and the nozzle plate 3 are electrically connected to each other. It is in contact. Therefore, when the atomized liquid is petroleum-based or the like, the contact between the negative electrode film 2b and the nozzle plate 3 becomes unstable due to deterioration of the resin adhesive, which tends to cause electrical contact failure, resulting in a lack of reliability. There was a problem.
