Abstract:
1. A thin-film capacitor comprising: plural first capacitative elements each having an electrode layer with a first polarity on an upper surface of a dielectric layer and an electrode layer with a second polarity on a lower surface of the dielectric layer and arranged around a specific position; plural second capacitative elements each having an electrode layer with the second polarity on the upper surface of the dielectric layer and an electrode layer with the first polarity on the lower surface of the dielectric layer and arranged around the specific position alternately with the plural first capacitative elements; a single common connection hole provided in the specific position and connecting all electrode layers with the first polarity of the plural first capacitative elements and all electrode layers with the first polarity of the plural second capacitative elements; and plural individual connection holes provided around the common connection hole and connecting each electrode layer with the second polarity of the plural first capacitative elements to the adjacent electrode layer with the second polarity of the plural second capacitative elements.
