Title:
ESD PROTECTION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/018063
Kind Code:
A1
Abstract:
Provided is an ESD protection element with which it is possible to lower the discharge initiating voltage and improve resistance to the deterioration of insulating properties. This ESD protection element is provided with: a ceramic element body; a discharge auxiliary electrode embedded in the ceramic element body; a first discharge electrode that is embedded in the ceramic element body and is bonded to one main surface of the discharge auxiliary electrode; and a second discharge electrode that is embedded in the ceramic element body and is bonded to one main surface of the discharge auxiliary electrode so as to be separated from the first discharge electrode. The discharge auxiliary electrode contains: a first discharge auxiliary electrode that comprises a conductive member, is bonded to the first discharge electrode, and extends to the second discharge electrode side; and a second discharge auxiliary electrode comprising a conductive member that is smaller than that of the first discharge auxiliary electrode.
