PROBLEM TO BE SOLVED: To enable miniaturization of a DC-DC converter.SOLUTION: A DC-DC converter has an input terminal 9, an output terminal 10, a power converter 11 for converting a DC input voltage applied to the input terminal 9 to a DC output voltage having a predetermined level and outputting the DC output voltage to the output terminal 10, a noise filter unit 12 connected between the input terminal 9 and the power converter 11, a shield plate 13 having insulators 15 on both the surfaces thereof, and a metal case 14 in which the power converter 11, the noise filter unit 12 and the shield plate 13 are mounted. The power converter 11 and the noise filter unit 12 are laminated through the shield plate 13, and the negative-electrode side output terminal 16 of the power converter 11, the shield plate 13 and the metal case 14 are electrically connected to one another.SELECTED DRAWING: Figure 1 |
