ABSTRACT:
Internal electrodes A1to D1and A2to D2are laid in layers at spaces in the direction of thickness of a ceramic body1. Lead electrodes a1to d1and a2to d2are led out to a side face to form lead portions. Dummy electrodes51to58have one-side ends led out to a side face to form lead portions in layers provided with the internal electrodes A1to D1and A2to D2. The lead portion of a lead electrode a1to d1or a2to d2of each layer is superposed over the lead portion of a dummy electrode51to58belonging to another layer in the direction of thickness.
