<p><P>PROBLEM TO BE SOLVED: To provide an adhesive material reel capable of sufficiently inhibiting the transfer of an adhesive layer to the back surface of a substrate material on drawing out a circuit-connecting tape in a wound state and useful for the production of a circuit-connected body having an excellent connection reliability. <P>SOLUTION: This adhesive material reel equipped with a tape state substrate material and a circuit-connecting tape having an adhesive layer formed on the one side surface of the same and a winding core for winding the circuit-connecting tape is provided with that the circuit-connecting tape has a portion without forming the adhesive layer by at least over one round length of the winding core from the terminal end to the beginning end direction, and an end tape pasted to the terminal end part of the circuit-connecting tape so as to cover the portion, and extending/presenting from the final end part toward the winding core. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
