Can be rotated between the use position Ib projecting outward from one end edge of the desiccant pack D.
- the thermal bonding m may be performed by applying a hot melt material in advance to at least one of the opposing surfaces of one end portion of the humidity determination plate P and one end portion De of the desiccant pack D.
- the opposing surfaces are heated and pressed by a heating and pressing machine such as a thermal roll.
- the structure of the humidity indicator I (particularly the structure of the cover body C) is different from the first embodiment. That is, in this embodiment, the first and second resin films F 1 and F 2 constituting the cover body C of the humidity indicator I are formed to have the same dimensions and the same shape, and accordingly, the first resin film F 1 At one edge F 1 e, there is no extension 10 as in the first embodiment.
- the humidity indicator I is located between the standby position I a where the entire surface overlaps one side of the desiccant pack D, and the use position I b where most of the humidity indicator I projects outward from one edge of the desiccant pack D. Can be rotated.
- the thermal bonding ⁇ is, for example, a hot menoret material on at least one of the opposing surfaces of the outer surface of the one side end F 2 e of the second resin film F 2 and the one side end De of the desiccant pack D. Apply in advance and force the opposite surfaces with a hot pressing machine such as a hot roll! ] Performed by heat and pressure.
- the front air layer ⁇ u faces all of the plurality of humidity determination surfaces M 1 to M 4 as a common air layer and includes a plane including all of the humidity determination surfaces M 1 to M 4.
- the front air layer Au may be formed for each humidity determination surface or for each of several humidity determination surfaces. This also applies to the back side air layer Ad.
- the air judgment layer P is formed with the air layers A u and A d on the front side and the back side, respectively, but the back side air layer A d as the second air layer can be omitted. .
- the humidity determination surface M1 to M 4 may be directed to the inside, that is, the desiccant pack D side, because the humidity determination surface M 1 to M 4 can be brought closer to the desiccant pack D, so that the indicator I is defective. no This can be determined more reliably.
- cobalt chloride was illustrated as a moisture sensitive substance which forms the humidity determination surfaces M-M4 as a humidity determination part, in this invention, it uses other moisture sensitive substances which discolor by moisture absorption, and humidity. Determination surfaces M1 to M4 may be formed. In this case, the other moisture sensitive substance may be harmful to the human body or may be a moisture sensitive substance.
- the thermal bonding means is used as the bonding means.
- the bonding portion may be used without heating the bonding portion.
