て伸縮やはがれ等を生ずるという欠点があった。However, in such conventional devices, since the contact portions are brought into contact and short-circuited, poor conductivity occurs at the contact portions when moisture is absorbed, and sufficient reliability may not be obtained. Furthermore, since the electrode part has a sealed structure, it is not possible to easily clean the corrosion spots on the electrode surface caused by the special gas, the attached dust, etc., resulting in poor contact. Further, in this device, since the film and the electrode portion are laminated one above the other, there is a drawback that expansion and contraction or peeling may occur due to changes in the temperature and humidity environment.
