The first seal portion and the second seal portion are bonded together. The first contact portion and the second contact portion are in contact with each other in a contact region which surrounds the first inner portion and the second inner portion throughout their entire circumference. The first circuit member and the second circuit member are shut in a closed space which is enclosed by the first inner portion and the second inner portion. The first contact point and the second contact point are in contact with each other. ## Claims ### Claim 1 A device comprising a first film, a second film, a first circuit member and a second circuit member, wherein: the first film has a first inner portion and a first outer portion; the first inner portion is located inward of the first outer portion; the second film has a second inner portion and a second outer portion; the second inner portion is located inward of the second outer portion; the first outer portion has a first seal portion and a first contact portion; the second outer portion has a second seal portion and a second contact portion; the first seal portion and the second seal portion are bonded together to form a seal trace; the first contact portion and the second contact portion are in contact with each other in a contact region; the contact region surrounds the first inner portion and the second inner portion throughout their entire circumference; the device is formed with a closed space which is enclosed by the first inner portion and the second inner portion; the first circuit member and the second circuit member are shut in the closed space; the first circuit member comprises a first contact point; the second circuit member comprises a second contact point; and the first contact point and the second contact point are in contact with each other. ### Claim 2 (depends on 1) The device as recited in claim 1, wherein the first seal portion and the second seal portion are bonded together by heat-sealing. ### Claim 3 (depends on 2) The device as recited in claim 2, wherein each of the first film and the second film includes two layers consisting of a meltable layer which is meltable by the heat-sealing and an unmeltable layer which is not meltable by the heat-sealing. ### Claim 4 (depends on 1) The device as recited in claim 1, wherein: the first file and the second film are two sheet pieces of a single film member which overlap with each other; the film member has a predetermined portion and a cutting edge; the first file and the second film are connected to each other at the predetermined portion; and the seal trace is formed at least between the contact portion and the cutting edge. ### Claim 5 (depends on 4) The device as recited in claim 4, wherein: the film member is a single planar sheet; and the first file and the second film are the two sheet pieces which are folded at the predetermined portion to overlap with each other. ### Claim 6 (depends on 4) The device as recited in claim 4, wherein: the film member is a single folder-like sheet; and the first file and the second film are the two sheet pieces which are connected to each other at the predetermined portion. ### Claim 7 (depends on 1) The device as recited in claim 1, wherein: the first circuit member has a first base portion and a first conductive pattern; the first base portion is formed of an insulation film; the first conductive pattern is formed on the first base portion and has the first contact point; the second circuit member has a second base portion and a second conductive pattern; the second base portion is formed of an insulation film; and the second conductive pattern is formed on the second base portion and has the second contact point. ### Claim 8 (depends on 1) The device as recited in claim 1 wherein each of the first film and the second film has a high barrier property. ### Claim 9 (depends on 8) The device as recited in claim 8 wherein each of the first film and the second film has a high barrier property against oxygen. ### Claim 10 (depends on 8) The device as recited in claim 8 wherein each of the first film and the second film has a high barrier property against water vapor. ### Claim 11 (depends on 1) The device as recited in claim 1 wherein: the device comprises one or more elastic members; the elastic members are shut in the closed space; the elastic members include at least one of a first elastic member and a second elastic member; the first elastic member is, at least in part, located between the first film and the first contact point; and the second elastic member is, at least in part, located between the second film and the second contact point. ### Claim 12 (depends on 11) The device as recited in claim 11 wherein: each of the elastic members has a body and two main surfaces; the two main surfaces of each of the elastic members are located opposite to each other in a predetermined direction across the body; and for each of the elastic members, when the body is compressed so that the two main surfaces are close to each other in the predetermined direction, a part of air contained in the body is discharged, and when compressing of the body is stopped, air flows into the body. ### Claim 13 (depends on 12) The device as recited in claim 12 wherein each of the elastic members is an open-cell structure. ### Claim 14 A forming method of a device comprising a first film, a second film, a first circuit member and a second circuit member, the forming method comprising: preparing the first film, the second film, the first circuit member and the second circuit member, the first circuit member comprising a first contact point, the second circuit member comprising a second contact point; arranging the first film, the first circuit member, the second circuit member and the second film, which are stacked in this order, in a chamber while the first contact point and the second contact point face each other; and sealing the first film and the second film under a state where the chamber is vacuumed, so that the first circuit member and the second circuit member are shut in a closed space enclosed by the first film and the second film, and the first contact point and the second contact point are brought into contact with each other. ### Claim 15 (depends on 14) The forming method as recited in claim 14 wherein in the sealing, the first film and the second film are heat-sealed.
