Abstract
A submergence detection portion,is provided in a circuit substrate, or the like, which carries electronic circuits of a power window control portion. The submergence detection portion,is configured to have an elliptical hole portion,provided in the circuit substrate so as to be immersed in water in case of submergence of a vehicle, and electrically conductive patterns,and,provided in the circuit substrate so as to be opposite to each other with respect to the hole portion,. End portions of the electrically conductive patterns,and,near to the hole portion,are formed as electrically conductive pads,and,made of electrically conductive portions exposed. When the hole portion,is filled with water in case of submergence, the electrically conductive patterns,and,are electrically connected to each other. One of the electrically conductive patterns,and,is connected to a ground wiring pattern whereas the other is connected to a detection signal output circuit which outputs a submergence detection signal when the electrically conductive patterns,and,are electrically connected to each other.
