あつた。 In order to reliably seal the edges of the material group, that is, the membrane envelope, as shown in FIG. It is necessary to fill the space between the material 1 and the permeate flow path material 2. In particular, due to uneven winding of the material group, a large gap may occur between the permeable membrane 1 and the permeate channel material 2, and the adhesive filled in the gap may flow out, resulting in poor sealing. Sometimes this occurred. However, an adhesive for end face sealing that can sufficiently solve the above-mentioned disadvantages has not yet been obtained. For this reason, for example, a method has been adopted in which the sealing part of the permeable membrane is made into a film by heat fusion, etc. to make it impermeable, and then this part is sealed with an adhesive with low fluidity, but the manufacturing process is complicated. It had the disadvantage of becoming.

In this sense, in the present invention, 2
A low fluidity layer is substantially formed by the above two types of adhesives, and the high fluidity adhesive does not need to flow out outside the application area. It is also possible to use a combination of highly fluid adhesives that immediately undergo a curing reaction to form a low fluid layer. After the adhesive has hardened, if necessary, cut both end faces with

It is sufficient if the fluid adhesive and the low fluidity adhesive can be cured, and the application form of the high fluidity adhesive and the low fluidity adhesive can be modified in addition to the above description. For example, the high fluidity adhesive It is also possible to prevent the high-flow adhesive from flowing outside the application area by applying a low-flow adhesive approximately parallel to both sides of the application area. There is no need to stand up.
