A plurality of internal electrodes (17, 18) are formed in a laminated state with a respective dielectric layer (12b, 12c) held between each pair of adjacent internal electrodes to give capacitance. A pair of external electrodes (15, 16) are electrically connected to associated internal electrodes in order to connect the capacitance to external circuits. Each internal electrode comprises a capacitance forming portion (19, 22) a take-out (external connection) portion (20, 23) connected to the associated external electrode, and a fuse portion (21, 24) which electrically interconnects the capacitance forming portion and take-out portion. The fuse portion is melted earlier than the capacitance forming portion and take-out portion by the Joule heat produced when a current higher than a predetermined value flows through the fuse portion.
