<p>Inside an insulating multilayer substrate 12 in which a plurality of insulating layers are laminated, a cavity portion 13, at least one pair of discharge electrodes 14 and 15, and conductor portions 34 and 35 are formed. The discharge electrodes 14 and 15 are connected to external electrodes 18 and 19 and have facing portions 14a and 15a which are formed along an inner surface of the cavity portion 13 and which face each other with a space provided therebetween. The conductor portions 34 and 35 are formed to cover at least one of facing front ends 14s and 15s of the facing portions 14a and 15a of the discharge electrodes 14 and 15 when viewed in a lamination direction of the insulating layers, a facing direction of the facing portions 14a and 15a, or a direction perpendicular both to the lamination direction and the facing direction.</p> |
