<P>PROBLEM TO BE SOLVED: To provide a filter attachment seal, which hardly causes leaving of adhesive when removing a filter, and never impairs the permeability of the filter, and a filter structure. <P>SOLUTION: The filter attachment seal 10 includes: a sheet-like seal body 11, a first adhesive layer 15 formed on one surface of the seal body 11, and a second adhesive layer 16 formed on the other surface of the seal body 11. The adhesive force of the first adhesive layer 15 is set larger than that of the second adhesive layer 16. In use, the filter attachment seal 10 is attached to the vicinity of the outer edge of a filter 1 made from nonwoven fabric by the adhesive force of the first adhesive layer 15 to constitute the filter structure 60, and attached to a flange 82 through the adhesive force of the second adhesive layer 16. Since the adhesive force to the filter 1 is larger than the adhesive force to the flange 82 in the seal body 11, adhesive leaving of the second adhesive layer 16 is hardly caused when the filter 1 is removed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
