<p>An adhesive sheet for dicing comprising a base film provided at least one surface thereof with an adhesive layer, wherein the base film comprises an olefinic thermoplastic elastomer comprising propylene and ethylene and/or alpha -olefin including 4 to 8 carbon atoms as polymerization components, and the peak melting temperature of the olefinic thermoplastic elastomer is 120 DEG C or more, is free of economical disadvantages with less reduction in the quality level of products and less generation of fibrous off-cuts during dicing. In particular, fibrous off-cuts occur less during dicing when the base film contains a crystal-nucleating agent. Further, generation of chippings during dicing can be prevented by incorporation of an ethylene series polymer into the base film. <IMAGE></p> |
