Abstract
An ESD protection device includes first and second discharge electrodes and a discharge auxiliary electrode that is electrically connected to the first and second discharge electrodes. The first and second discharge electrodes are located on or in an insulating substrate to at least partially face each other. The discharge auxiliary electrode includes first metal particles, second metal particles, and a binding agent. The first metal particles have a core-shell structure including a core section mainly including a first metal and a shell section which mainly includes an oxide of a second metal and which includes at least one portion with a cavity. The second metal particles have a core-shell structure including a core section mainly including the first metal and a shell section which mainly includes the oxide of the second metal and which has no cavity.
