Abstract
The double-sided pressure-sensitive adhesive tape or sheet is a double-sided pressure-sensitive adhesive tape or sheet containing a support having a pressure-sensitive adhesive layer on the both surfaces thereof, characterized in that the double-sided pressure-sensitive adhesive tape or sheet has a total thickness including the thickness of the support and the two pressure-sensitive adhesive layers formed on the both surfaces of the support of 0.003 mm or more and less than 0.03 mm and a breaking strength of from 2 to 26 MPa/10 mm-width. The support preferably has a thickness of from 0.002 to 0.012 mm. As the support, plastic films (especially, a polyethylene terephthalate film) are suitable. The double-sided pressure-sensitive adhesive tape or sheet may have a length of 5 m or more and have a roll-wound form.
