CAPACITIVE HUMIDITY-SENSOR AND CAPACITIVE HUMIDITY-SENSOR MANUFACTURING METHOD

摘要

A capacitive humidity sensor comprising a humidity-sensitive film made of an organic polymer resin and provided on a conductive base serving as a lower electrode, a water-molecule-permeable upper electrode provided on the humidity-sensitive film, and a lead wire electrically connected to the upper electrode is characterized in that the area of the junction of the upper electrode and the lead wire is 2.5 mm2 or less and/or 10% or less of the total area of the upper electrode.
