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 substrate serving as a lower electrode, a moisture 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 for the junction of the upper electrode and the lead wire is 2.5 mm<2> or less and/or 10 % or less of the total area of the upper electrode.
