PROBLEM TO BE SOLVED: To dissolve a problem that there is no method to confirm humidity of a refrigerating chamber by a user for a refrigerator since humidity is non- visible though the increase of humidity in a conventional refrigerating chamber is practicable. SOLUTION: A dry and wet display sheet 10 containing a pigment the color of which is changed according to a change of humidity is situated at the whole or a part of a refrigerating chamber shelf 4 of a refrigerating chamber 3 or at an inner box 2 of the refrigerating chamber. This constitution causes a user to simply recognize humidity in the refrigerating chamber by changing the color of the dry and wet display sheet 10 according to a change of humidity in the refrigerating chamber. |
