STRUCTURE AND MANUFACTURE THEREOF

PROBLEM TO BE SOLVED: To secure a good adhesion condition and high adhesive strength by forming vents in one backing to be dispersed and sticking both backings together when the residual amount of an adhesive is in a specified range to the initial amount of a solvent in sticking the first and second backings together with a solvent type adhesive. SOLUTION: A structure 1 is composed of a first backing 2, a second backing 3, and an adhesive layer 4 placed between the first backing 2 and the second backing 3. At least in one of the first backing 2 and the second backing 3, for example, in the first backing 2, vents 5 consisting of through holes are formed to be dispersed appropriately. In this way, after a solvent type adhesive being applied, when both backings 2, 3 are stuck to be bonded together, the solvent in the adhesive is released through the vents 5 to bring about a condition in which no solvent is in the adhesive layer 4 after the completion of adhesion, and before the completion of adhesion, an appropriate solvent is made to remain in the adhesive. After the adhesive being applied, the residual amount of the solvent in the adhesive when the sticking of the backings 2, 3 is started is made 10-20wt.% of the initial amount of the solvent.
