Abstract
The present invention is to provide a small-sized dryness/wetness responsive sensor that detects a galvanic current with a high sensitivity as a principle of operation. According to one embodiment of the present invention, a dryness/wetness responsive sensor comprises a thin wire made of a first metal and a thin wire made of a second metal, the second metal is different from the first metal, the thin wire of the first metal and the thin wire of the second metal are disposed in juxtaposition with each other on an insulating substrate, and a surface state of a part between the thin wire of the first metal and the thin wire of the second metal is hydrophilic or hydrophobic.
