Title: ESD PROTECTION ELEMENT
Abstract:
This ESD protection element (101) is provided with: a laminate (81) formed by laminating a plurality of substrate layers which are unfired ceramic layers; a first external terminal (P11) and a second external terminal (P21) formed on the surface of the laminate (81); a cavity (41) formed inside the laminate (81); a first discharge electrode (11a), a portion of which is exposed inside the cavity (41); a second discharge electrode (21a) facing the first discharge electrode (11a), a portion of the second discharge electrode (21a) being exposed inside the cavity (41); a first lead-out conductor (11b) connected to the first discharge electrode (11a) and the first external terminal (P11); and a second lead-out conductor (21b) connected to the second discharge electrode (21a) and the second external terminal (P21). The first lead-out conductor (11b) and the second lead-out conductor (21b) are made of a material having a higher adhesion force to the substrate layers than those of the first discharge electrode (11a) and the second discharge electrode (21a).
