(Amendments Included) SUBJECT of the Invention In the connection of a veneer core, a monofilament is unnecessary and it provides the tape which can be provided in a short time. PROBLEM to be solved The wide tape 1 for a veneer core connection is mounted on the upper surface of a connection part, heat and a pressure are applied, and it adhere|attaches strongly|forcefully. The tape 1 cuts|judges what pierced the many hole 4 on the sheet|seat which consists of two layers, the nonwoven fabric 2 of fabric weight 25g/m 2-50g/m2, and the hot-melt-adhesive layer 3, in width of 31-52 mm, It is the structure wound as the roll 5. Radiant raies, such as a far-infrared heater, are applied to the hot-melt layer 3 side of the tape 1, and a hot-melt-adhesive is dissolve|melted, and with a rubber roll, it is strongly crimped|bonded to a veneer|single_plate by pressure, and adhere|attaches. In addition, by having pierced the many hole using the nonwoven fabric, an adhesive agent liquid infiltrates to a nonwoven fabric, and it is effective in entering a hole, hardening|curing and adhere|attaching veneer|single_plates strongly.
