[Embodiment of the invention] Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 4. Fig. 1 is a plan view of the conveying sheet, Fig. 2 is a cross-sectional view along the sheet and the conveying direction, and Fig. 3 is a sectional view along the (4) sheet X * degree direction. "Fig. 4 is a schematic diagram of the manufacturing process. The dimension magnification of the thickness direction in each figure of the plane is larger than the plane direction. As shown in FIG. 1, the part 1 of the sheet 1 with the right w 'point plate and the traditional example @' is made by the upper pu 9. ^ The thick sheet, the spacer sheet 3 attached to the bottom sheet 2 and the Akan plate The structure 4 is described as follows: The contact plate 4 is adhered to the lower surface of the upper sheet 2 and is inserted into the through hole 5 provided in the thin film. The upper sheet 2 is composed of an upper sheet 2a and an upper examination layer 2b, and the # and the name π s wide are bonded to the spacer sheet 3 through the upper adhesive layer 2b. ^ 2 sheet 3 is formed of a spacer film 3a and a spacer adhesive layer 3b. In addition, the sheet body 1 has a through hole 6 provided for assembling a member such as LED. The sheet 1 having the above-mentioned structure is adhered to the band-shaped heart diaphragm 7 by the spacer adhesive layer 3b, and so far it is similar to the prior art. However, the transfer sheet (not shown in FIG. 2) is formed of a transfer sheet 7a and a transfer adhesive layer 7b, and a strip-shaped protective sheet 8 is attached under the sheet. However, the protective sheet 8 is not provided with an adhesive layer. The existing technology is different. Therefore, no spotting agent is adhered to the outer peripheral portion below the contact plate 4, and as shown in FIG. 3, the portions on both sides of the X-direction conveying partition plate 7b remaining under the positioning hole 8 are used to convey the thin film 7 'When rolled on the drum, there was no sticking to each other. Hereinafter, the manufacturing process of the above-mentioned structure will be described based on FIG. 4. First, the transfer sheet 7a, the transfer adhesive layer 7b, and the transfer partition 7d are laminated, and the transfer sheet 7 is placed in a state of being wound on a drum 7R, and then pulled into a line. On the other hand, the spacer sheet 3 laminated with the spacer film 3a, the spacer adhesive layer 3b, and the spacer 3c is placed in a state of being wound on a roll 3R, and then pulled out. After being pulled out, the spacers were immediately peeled away and connected to the thin transfer sheet. The 4c sheet was sent and separated by the separation 200302498 (5) into a residual sheet and rolled onto the roller 3S. After the conveyance sheet 7 and the spacer sheet 3 are adhered together, a positioning hole 7c and a through hole 5 of the contact plate are processed by the punch 5P. At this time, since the transfer adhesive layer 7b is formed of a weakly adhesive material, it is difficult to adhere to the processing device (the same applies to the following processing). When the upper sheet 2a laminated with the upper sheet 2a, the upper adhesive layer 2b, and the upper partition 2c is pulled out from the roller 2R, the upper partition 2c is immediately peeled off, and the residual sheet is rolled onto the roller 2S. The remaining upper sheet 2a and the upper adhesive layer 2b are adhered to the spacer sheet 3. A cutout is formed in the outer shape of the sheet 1 by a semi-circular punch 1. At the same time, the through hole 6 is punched out by the punch 6P. Then, the useless parts of the upper sheet 2 and the spacer sheet 3 are peeled off together, and are wound onto the drum 2T as a residual sheet. The contact plate 4 is inserted into the through-hole 5 from the lower surface of the residual sheet 1 by an inserter 41 and adhered to the lower surface of the upper adhesive layer 2b. Then, the conveying partition 7d with the through hole empty is taken up as a scrap, leaving only the portion on the lower side of the positioning hole 7c of the conveying sheet 7. And the lower surface of the conveyance sheet 7 (except the part on the lower side of the positioning hole 7c) is covered by the protective sheet 8 supplied from the roller 8R. Finally, the finished product is wound into the drum 7T. Next, a second embodiment of the present invention will be described with reference to Figs. 5 to 8. Fig. 5 is a plan view of the conveyed sheet, Fig. 6 is a sectional view along the sheet conveying direction, Fig. 7 is a sectional view of the sheet width direction, and Fig. 8 is a schematic view of a manufacturing process. The description of the same parts as those of the first embodiment will be omitted. Compared with Example 1 to which the dot plate sheet is attached, the difference is that there is no spacer sheet 3. In this case, when the user connects on the product substrate, a part of the contact plate 4 of the upper sheet 2 projects in a convex shape. In addition, neither the transfer sheet 7 nor the protective sheet 200302498 (6) sheet 8 has an adhesive layer. Therefore, in order to fix the protective sheet 8 to the conveying sheet 7, the fixing sheet 9 is adhered. This fixed sheet 9 is formed of a fixed sheet 9a and a fixed adhesive layer 9b, and its width is narrower than the transport sheet 7 and wider than the protective sheet 8. Therefore, the protective sheet 8 is held under the transport sheet 7. According to the above structure, there is no need to worry about the contact of the outer peripheral portion 4c on the lower side of the contact plate 4 with the adhesive as in the previous embodiment. The manufacturing process of Example 2 will be described below. First, the conveyance sheet 7 is placed in a state wound on a drum 7R, and then pulled into a processing line. The conveying sheet 7 punches out the positioning hole 7c and the through hole 5 of the contact board through the punch 5P. Then, the upper sheet 2 formed by laminating the upper sheet 2a, the upper adhesive layer 2b, and the upper partition 2c is pulled out from the roller 2R, and the upper partition 2c is immediately peeled into a residual sheet and rolled onto the roller 2S. And adhered to the conveyance sheet 7. A semi-circular punch 1 is used to form a cutout in a part of the outer shape of the sheet body 1, and a punch 6 is punched out of the through hole 6 at the same time. Then, the useless part of the upper sheet 2 is peeled off, and it is rolled into the drum 2T as a scrap. The contact plate 4 is inserted into the through hole 5 from the lower surface of the residual sheet 1 by an inserter 41 and is bonded to the lower surface of the upper sheet 2a. The fixed sheet 9 formed of the fixed sheet 9a, the fixed adhesive layer 9b, and the fixed partition 9c and having a width smaller than the distance between the positioning holes 7c on both sides of the conveyance sheet 7 is pulled out from the roller 9R. Since the fixing sheet 9 does not cover the positioning holes 7c of the conveying sheet 7, the processing device-side positioning pins inserted into the positioning holes 7c are not contaminated by the drilling agent. Therefore, product accuracy and yield are improved. And the fixed partition 9c is immediately rolled into the drum 9S as a residue; the fixed adhesive layer 9b is on one side, and a protective sheet 8 having a narrow width is adhered; The sides are glued. Finally, the finished product was -10-200302498

⑺ Roll onto the roller 7T. In the above-mentioned embodiment, the conveying sheet 7 is continuous, and it may be processed discretely. In addition, in this embodiment, only the contact board 4 is inserted at the through hole 5, but it is not limited to this method. Electronic components with electrodes can be installed together, and the effect is the same. Alternatively, a sheet-like material having various functions may be laminated on the upper sheet. The shape of the contact plate is not limited to a downwardly-shaped bowl-shaped structure, and may have various other applicable shapes.
