<p>In a feedthrough capacitor, a signal internal electrode layer is so arranged that an opposed portion opposed to a ground internal electrode layer is provided with a projection projecting toward a ground electrode, when viewed from a direction of a stack of dielectric layers. Therefore, if a gap amount G is abnormal between an end face with the ground electrode thereon and the signal internal electrode layer, the projection comes in contact with the ground electrode and a short circuit occurs between the ground electrode and terminal electrodes. This feedthrough capacitor thus permits easy detection of abnormality of the gap amount G, based on the presence/absence of a short-circuit failure.</p> |
