A high molecular humidity sensor in which polypyrrole being of conductive high molecule is electrochemically polymerized and then reduced whereby ionic conductive property is given go that humidity sensibility becomes excellent. The sensor is a structure in which polypyrrole doped with dodecylsulfate anion DS.sup.- is stuck in film form on the surface of a fine electrode, and cations Na.sup.+, K.sup.+ are permeated to said polypyrrole whereby salt is formed and humidity sensibility is exhibited in the region of 10.sup.4 -10.sup.6 .OMEGA., and humidity sensing speed becomes within several tens of seconds to several minutes.
