C4, etc.) to improve soundproofing and heat insulation. If the internal gas leaks and the outside air intrudes into the interior, the soundproofing and insulation effects of this gas will decrease, so if the internal gas leaks and the outside air intrudes, this will be detected and repaired. There is a need to. Therefore, the above-mentioned actual application 1
In e57-1379889, the present applicant provides a device in which a moisture sensor is formed of a detection paper to which cobalt chloride is attached, and this moisture sensor is mounted inside a multilayer panel B. 7:l:. In other words, if internal gas leaks and outside air intrudes, the cobalt chloride gas detector of the paper detects moisture in the outside air, but since the moisture adsorption capacity of the paper is low, even if only a small amount of gas leaks, it will not be able to detect cobalt chloride. Since the effect of moisture was small and the cobalt chloride did not change color, sensitive detection of gas leakage was not possible.

形成さり。For example, cobalt chloride can be used as a moisture sensing material. Chloride:] Bapal exhibits a cobalt color, but it has the property of changing color to pink or negative when it absorbs moisture. This moisture sensing material is attached to porous particles such as silica gel. First, cobalt chloride is thoroughly stirred with water in a container to prepare a cobalt chloride aqueous solution, and porous particles such as silica gel are attached to the cobalt chloride aqueous solution. The pores of the porous particles are impregnated with a moisture sensing material such as cobalt chloride. Next, put the deko'h in a hot air dryer or the like to dry it and evaporate the moisture. Adhesive is mixed with porous particles impregnated with moisture sensing material in this way,
Put this into a predetermined mold f1. It is hardened and made into a block shape, which is then cut into a forest shape (disk shape, square plate shape, etc.)
or into a columnar shape (cylindrical, prismatic, etc.). Of course, it can also be formed into any other shape. After drying the moisture sensing body formed in this manner, it is sealed in a moisture-proof film bag and used for storage or sale. As shown in the figure, a soft spacer (2) is sandwiched between two transparent glass plates (1) (1), and a gas such as halogenated hydrocarbon gas, such as fluorinated hydrocarbon gas, is sealed inside. It is used by pasting it inside a four-hole layered panel R3.When the internal gas leaks and the outside air enters, the humidity sensor A is detected by the moisture that enters with the outside air. The moisture sensing material inside changes color and gas leakage is detected.However, even if the mound is slightly dry and the amount of moisture intruding is small, the moisture sensing material A is detected.
Because of their porous nature, the porous particles have hygroscopic properties, and moisture is absorbed into the pores of the porous particles and acts on the moisture sensing material, making moisture detection sensitive. This makes it possible to use it even with the slightest leak of gas.
This allows early detection of gas leaks. In addition, (3) in Fig. 1 is a soft inverted sealing valve with a through hole (4) K that is provided through the glass plate (1). (As shown in Figure 2, the injection needle (5) (5) is attached to the sealing valve +3+ +31.
), the gas inside the multilayer panel B is removed from one injection needle (5), and a gas such as fluorinated hydrocarbon gas is injected from the other injection needle (5). Here, the moisture sensor A is formed into a predetermined shape by assembling a large number of porous particles with an adhesive.

- Due to the inflow of gas (1-2), there are some products that scatter and cannot be used for practical purposes. In this case, in order for moisture to act on the moisture detecting body A, it is necessary to pass through the bag7, making it impossible to detect moisture sensitively. In addition, in the moisture detecting body A in the present invention, the moisture detecting material is impregnated into the pores of the porous particles, so a large amount of the moisture detecting material can be attached to the porous particles, and the moisture detecting material can be used for a long period of time. The humidity sensing element A can be used repeatedly by heating to evaporate absorbed moisture.

It can be used for a long period of time without having to worry about complemen- turing it.In addition, such a moisture detector can be easily and inexpensively manufactured by molding it using adhesive.
