<p>PROBLEM TO BE SOLVED: To provide a technology of preventing noise due to vibration of a capacitor from entering the inside of a vehicle.SOLUTION: In an installation structure of a capacitor 20, a plurality of capacitors 20 are housed in a capacitor case 30, with larger wound surfaces 20a of flat wound surfaces 20a, 20b, which are formed by winding a metal film in a flat shape, facing an opening 30a of the capacitor case 30. A potting material 50 charged between the capacitor case 30 and the capacitors 20 covers the opening 30a. The structure is mounted on an electric vehicle, with the opening 30a facing outward. A flat wound surface 20a which is likely to be vibrated faces the opening 30a of the capacitor case 30, thereby emitting noise due to the vibration to the outside of the capacitor case 30. The emitted noise is transmitted not inward but outward. The noise due to the vibration of the capacitor 20 is prevented from entering the inside of the vehicle, accordingly.</p> |
