<p><P>PROBLEM TO BE SOLVED: To provide a circuit board unit capable of reducing unnecessary resonance sound even when a normal ceramic capacitor is used without having a special additional member such as a metallic plate. <P>SOLUTION: The circuit board unit includes: a board; and an electronic component mounted on the surface of the board, and having a first electrode at one end and a second electrode at the other end. The board includes through-holes penetrating the board at a position adjacent to the first electrode and a position adjacent to the second electrode, which are respectively arranged to be substantially symmetrical. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
