Abstract
A circuit board having a printed capacitor whose capacitance is easily adjusted includes a plurality of through-holes arranged in arrays and electrically connected to each other via conductive films. Therefore, first and second electrode portions are arranged to oppose each other, and form a printed capacitor. The capacitance of the capacitor can be adjusted by the number and diameter of through-holes, and the interval between each two adjacent through-holes. Therefore, even when a large-capacitance capacitor is to be formed, the printed capacitor can be rendered compact.
