PROBLEM TO BE SOLVED: To provide a laminated capacitor which has a low capacitance, a high Q-value, and no internal structural defect. SOLUTION: Electrode pairs 26, each of which is constituted by arranging two internal electrodes 22 connected to one external electrode 24 in parallel with each other with a dielectric layer in between, and electrode pairs, each of which is constituted by arranging two internal electrodes 22 connected to another external electrode 24 in parallel each other with a dielectric layer 25 in between, are alternately laminated upon another with dielectric layers 21 in between. In addition, the dielectric constantε1 of the dielectric substance used for forming the layers 25 is set at a value higher than the dielectric constantε2 of the dielectric substance used for forming the layers 21 (ε1>ε2). Therefore, a high Q-value can be obtained in a high-frequency region and, at the same time, the internal stress strain of a laminated capacitor can be dispersed, because the eddy current losses which occur in the internal electrodes 22 become smaller and the resistance of each internal electrode piece can be set at a low value. In addition, the occurrence of a structural defect, such as the crack, delamination, etc., can be prevented.
