<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive tape or sheet for fixing wirings having excellent pressure-sensitive adhesive characteristics at low to high temperatures and excellent adhesion to rough surfaces and exhibiting excellent workability. <P>SOLUTION: The pressure-sensitive tape or sheet for fixing wirings is a pressure-sensitive tape or sheet used for fixing the wirings, having an adhesive layer formed on one surface of a substrate. The substrate is subjected to release treatment at the back surface and has a tensile strength of ≥10 N/20 mm (in MD direction in conformity to JIS Z 1702 at 23°C and 50% RH), and the adhesive layer is formed of an acrylic adhesive composition containing an acrylic polymer containing an alkyl (meth)acrylate having a 2-18C alkyl group as a principal monomer component and a tackifying resin composed of a polymer rosin ester and having a softening point of 80-170°C. <P>COPYRIGHT: (C)2008,JPO&INPIT |
