PURPOSE:To improve response and hysteresis characteristics, by constituting a humidity sensitive resistance film from a hydrophilic polymer containing one or more ion of a metal selected from vanadium, chromium, manganese, iron, cobalt, nickel, copper and zinc and a conductive powder. CONSTITUTION:One or more ion of a metal selected from vanadium, chromium, manganese, iron, cobalt, nickel, copper and zinc is contained in a humidity sensitive film containing a hydrophilic polymer and a conductive powder and these ions are unevenly distributed to the surface layer part thereof or contained in the whole to form chelate in a molecule. By this method, a high-molecular chain is crimped to ascertain the mutual contact of conductive particles and the swelling of the hydrophilic polymer during moisture adsorption is increased to enlarge the change in resistance increase. |
