PURPOSE:To perform accurate humidity detection, by forming a moisture sensitive element by a moisture sensitive part and lead terminals provided at the moisture sensitive part, supporting lead wires by a case, which encloses the moisture sensitive element, and constituting the outer surface of the moisture sensitive part and the inner wall of the case so that they are not contacted. CONSTITUTION:A moisture sensitive element 30 is formed by a moisture sensitive part 301 and lead terminals 302 and 303. The element 30 is supported by a case 1 so that the outer surface of the moisture sensitive part 301 is not contacted with the case. A case 100 is formed on the right and left sides of a hinge part 103 and a sensor 10 is housed in the box shaped case 100 having an opening 101. The moisture sensitive element 30 is positioned in a space formed by the boxes. The moisture sensitive surface is positioned so as to face the opposite surface with respect to the opening 101. The lead terminals 302 and 303 of the moisture sensitive element 30 are connected to lead wires 50. They are held by a taking-out groove 109 and a lead pushing projection 111. Thus useless operation is eliminated and automatic stopping function can be imparted. |
