<p>A humidity indicator comprising a coloration composition, which contains a deliquescent material, supported on a porous base material, wherein the adhesion of the coloration composition, which has been once printed and thus adhered to the base material, to a member or the like of a printer is inhibited in a production process to thereby reduce printing errors and the maintenance frequency of the printer. Furthermore, blocking which occurs in stacking multiple humidity indicators can be prevented. Beads (3) not reacting with the constituting components of the coloration composition (4) are dispersed into the coloration composition to form convex portions. Further, the coloration composition (4) is coated with a top coat layer (5) comprising beads (6) dispersed in a resin (7).</p> |
