A low-cost leak sensor that prevents leakage current from flowing between electrodes when moisture is deposited. A leak sensor is formed on an insulating substrate. The leak sensor has a through hole having a pair of opposed walls with a predetermined space. The opposed walls are provided with conducting films. On the opening of the through hole in the insulating substrate, a pair of lands are connected electrically with the pair of conducting films. A pair of wiring patterns are connected electrically with the pair of lands on the insulating substrate.
