<p>PROBLEM TO BE SOLVED: To decrease the production cost, to improve the efficiency in the process of sticking an adhesive layer and to increase the reliability of connection between a TAB film and a circuit board by sticking plural adhesive layers corresponding to a specified position of each circuit board over the all circuit boards of a connected circuit board. SOLUTION: An adhesive layer laminated body 1 has a structure of three layers consisting of a first release paper 2 comprising a transparent polyester film subjected to surface treatment with silicone, a colored adhesive layer 3, and a second opaque release paper 4 subjected to surface treatment with silicone. The plural adhesive layers 3 are arranged corresponding to a given position of plural circuit boards and can be laminated over plural circuit boards. Thereby, plural numbers of circuit boards with adhesive layers can be produced at one time and thereby, the circuit board with the adhesive layer can be produced at a low cost. It is preferable that the width direction of the first release paper 2 and the longitudinal direction of the adhesive layer 3 are almost parallel to each other. Thereby, adhesion of the laminated toady to a connected circuit board and peeling of the first release paper 2 can be easily performed.</p> |
