Abstract
A connection device for connecting a first power supply and a second power supply to an ignition plug has a first power supply side line which establishes electrical connection between the ignition plug and the first power supply and which is electrically connected to the second power supply, and a second power supply side line which establishes electrical connection between the ignition plug and the second power supply. The first power supply side line includes a first diode which prevents a current inflow from the second power supply into the first power supply or a current inflow from the first power supply into the second power supply, and an inductor disposed between the first diode and the ignition plug. The inductor is disposed around the second power supply side line while being separated from the second power supply side line. Thus, noise can be suppressed.
