  • Publication number: 20150223369
    Abstract: An electrostatic protection element is provided with: a pair of discharge electrodes that are provided on an insulating substrate; and a discharge auxiliary electrode that connects the discharge electrodes to each other so as to link a discharge gap D between the discharge electrodes. The discharge auxiliary electrode has a varistor function with zinc oxide as a main component, and is formed by thick-film printing. The electrostatic protection element is provided with an insulating dome-forming layer with which a cavity portion is formed so as to cover the discharge gap D. The dome-forming layer is formed of glass ceramics, and is coated with a protection layer. The electrostatic protection element is capable of stably achieving a sufficient electrostatic protection function, and has a low electrostatic capacitance and a low discharge start voltage.
