<p>PROBLEM TO BE SOLVED: To provide a control device that is downsized and low-cost by decreasing the number of electrical connections which should be connected.SOLUTION: The control device includes a control circuit (100) and a housing (104) that is electrically connected directly or indirectly to a ground of a power supply (124) and houses the control circuit. The control circuit includes a plurality of ground junctions (140, 142, and 144) to which electrical components constituting the control circuit are connected. Only a ground junction through which a ground current equal to or larger than a predetermined current value flows out, or only a ground junction through which a ground current below the predetermined current value flows out, out of the plurality of ground junctions is electrically connected to the housing, and electrically connected to the ground of the power supply via the housing. The other ground junctions are connected to the ground of the power supply over lead wires (134b and 134c).</p> |
