ADHESIVE SHEET AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an adhesive sheet capable of achieving both an improvement in mechanical adhesive strength and an improvement in electrical connectivity, in the adhesion between a flexible printed wiring board and a reinforcement plate.SOLUTION: An adhesive sheet according to the present invention is an adhesive sheet which includes a conductive adhesive layer and bonds between a flexible printed wiring board and a reinforcement plate, and by which conductivity is exhibited in the reinforcement plate and a ground circuit of the flexible printed wiring board. The conductive adhesive layer includes: a conducting part exhibiting conductivity at least in the thickness direction thereof and made of a conductive paste; and an adhesive agent layer filled around the conducting part. The conducting part may be arranged in a scattered-point like manner or a linear like manner, in plan view. The conducting part may have a cross-sectional shape of a trapezoidal shape. The conducting part is disposed such that the top side of a trapezoidal shape is located on a reinforcement plate side. The conducting part may be also disposed such that the top side of a trapezoidal shape is located on a flexible printed wiring board side.
