MULTI-TERMINAL TYPE LAMINATED CAPACITOR AND MANUFACTURING METHOD THEREOF
Electrode layers 121 to 128 are superimposed in a ceramic porcelain 1 with ceramic layers therebetween. The electrode layers 121 to 128 respectively include internal electrodes A 1 to A 8 and extraction electrodes B 1 to B 8. Giving a description on the electrode layer 121, one end of the extraction electrode B 1 is connected with the internal electrode A 1 in the same layer, and the other end of the same is led onto a side surface of the ceramic porcelain 1. Further, the extraction electrode B 1 is formed to be thicker than the internal electrode A 1 in the same layer.
