Title:
導電性粘着テープ
Document Type and Number:
Japanese Patent JP5824478
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a conductive adhesive tape excellent in tackiness and conductivity even when an adhesive layer is made thin, and having excellent step-absorbing property and causing no lift from an adherend even when the tape is stuck to a step.SOLUTION: A conductive adhesive tape has an adhesive layer, and has a thickness of 15 to 160 μm, the layer comprises an adhesive that contains a spherical and/or spike-like conductive filler having an aspect ratio of 1.0 to 1.5 by 14 to 45 pts.wt. with respect to 100 pts.wt. of the whole solid content of the pressure-sensitive adhesive excluding the conductive filler, with the conductive filler occupying 90 wt.% or more in the whole filler in the pressure-sensitive adhesive. Particle sizes dand dof the conductive filler and the pressure-sensitive adhesive layer thickness satisfy a relationship of d>(adhesive layer thickness)>d.
