Abstract
The object of the invention is to provide a water immersion detecting circuit, which is free from false detection and is stable and highly sensitive in operation. There is provide a water immersion detecting circuit provided on a printed board of an electronic unit and used for detecting water immersion of the electronic unit based on a change of resistance generated between a pair of sensor electrodes for detecting water immersion P , p , wherein the pair of sensor electrodes P , P are positioned opposite to each other on the printed board , and a U-shaped slit (opening) is formed between the sensor electrodes P , P
