[SUBJECT] EVEN IF AN OPERATOR PICKS, WITH HIS OR HER HAND, A HUMIDITY INDICATOR FOR DETERMINING A HUMIDITY BY THE DISCOLORATION OF COBALT CHLORIDE, THE COBALT CHLORIDE ON A HUMIDITY-DETERMINING FACE IS PREVENTED EFFECTIVELY FROM ADHERING TO THE OPERATOR'S HAND AND THUS, ENTERING INTO HIS OR HER BODY. IN ADDITION, EVEN IF FINE DUST IS GENERATED FROM A BASE PAPER SHEET OF THE HUMIDITY INDICATOR, IT IS HARD FOR THE DUST TO BE DIFFUSED TO THE SURROUNDINGS, THEREBY EFFECTIVELY PREVENTING THE INFLUENCE OF THE DUST TO ELECTRONIC PARTS. @(MEANS FOR SOLUTION] A HUMIDITY INDICATOR INCLUDES A FIRST FILM F1 COVERING A SURFACE OF A HUMIDITY-DETERMINING PLATE P, AND A SECOND FILM F2 COVERING A BACK OF THE HUMIDITY-DETERMINING PLATE P. A FLAT AIR LAYER AU IS FORMED AT LEAST BETWEEN THE FIRST FILM F1 AND THE SURFACE OF THE HUMIDITY-DETERMINING PLATE P, SO THAT THE ENTIRE SURFACES OF HUMIDITY-DETERMINING FACES M1 TO M4, TO WHICH COBALT CHLORIDE IS EXPOSED, FACE TO THE AIR LAYER AU, AND A PLURALITY OF SMALL HOLES H ARE FORMED AT DISTANCES FROM ONE ANOTHER IN THE FIRST FILM F1 TO PERMIT THE DIRECT COMMUNICATION OF THE AIR LAYER AU WITH THE ATMOSPHERE.
