<p>PURPOSE: A double-sided adhesive tape is provided to suppress a degradation of shock resistance under a low temperature atmosphere when used for fixing an electronic device member. CONSTITUTION: A double-sided adhesive tape (10) comprises: a material (20); a first pressure-sensitive adhesive layer (30) installed on a side of the material; and a second pressure0sensitive adhesive layer (40) installed on the other side of the material. At least one of the first and second pressure-sensitive adhesive layers comprises: acrylic polymer; and acryl class oligomer whose weight-average molecular weight is under 20000, having a different monomer from the acryl class polymer. At least one of the first and second pressure-sensitive adhesive layers contains less than 5 wt% of a tackifier.</p> |
