Abstract
A combined unit of a humidity indicator and a desiccant pack is provided in which the humidity indicator (I) has one end portion bonded to one end portion of the desiccant pack (D) and can pivot around between a standby position (Ia) in which the indicator (I) overlaps one face of the desiccant pack (D) and an in-use position (Ib) in which it overhangs outside from one end edge (De) of the desiccant pack (D)), with the pivot center in the bonding portion or the vicinity thereof. This enables the humidity indicator to overlap the desiccant pack in the standby position when it is in an unused state, and after being enclosed within a packaging bag the humidity indicator and the desiccant pack can be kept as far away from each other as possible within the packaging bag, thus enabling detection of the humidity of the interior of the bag to be carried out precisely and appropriately.
