Abstract: The present invention provides a double-sided adhesive tape for fixing a decorative sheet for speaker, which includes a nonwoven fabric substrate, an acrylic pressure-sensitive adhesive layer A disposed on one side of the nonwoven fabric substrate and an acrylic pressure-sensitive adhesive layer B disposed on the other side of the nonwoven fabric substrate, in which the adhesive tape has a tensile strength in the tape flow (MD) direction of 8 N/10 mm or more and a tensile length in the width (TD) direction of 8 N/10 mm or more. The double-sided adhesive tape is excellent in the adhesion performance to a housing and a decorative sheet for speaker and at the same time, has excellent releasability ensuring that when separating the decorative sheet portion, smooth separation can be attained without leaving a residue of tape or pressure-sensitive adhesive on the housing portion.
