Double-sided adhesive tape

A double-sided adhesive tape comprising:

• a polyolefin foam base;
• a resin film disposed on a surface of the polyolefin foam base;
• an adhesive layer disposed on a surface of the resin film;
• an adhesive layer disposed on another surface of the polyolefin foam base;
• and a bonding-agent layer interposed between the polyolefin foam base and the resin film and dry-laminated so as to bond the foam base and the resin film to each other by a dry lamination method,
• the polyolefin foam base having a thickness of 250 μm or less, a density of 0.45 g/cm3 or less and a maximum strength of 10 N/cm or more, the adhesive layer having a 180° -peel adhesion of 10 N/20 mm or more, the 180° -peel adhesion of the adhesive layer being measured at a peeling speed of 300 mm/min when an adhesive tape including a 25-μm-thick polyethylene terephthalate base and a 25-μm-thick adhesive layer disposed on the polyethylene terephthalate base is bonded to an aluminium board under conditions of a temperature of 23° C. and a relative humidity of 65% RH by pressing the adhesive tape against the aluminium board with one stroke of a 2-kg roller, the adhesive tape is left standing for 1 hour under conditions of a temperature of 23° C. and a relative humidity of 50% RH, and subsequently the adhesive tape is left standing for 1 hour under conditions of a temperature of 23° C. and a relative humidity of 50% RH, wherein
• the maximum strength is measured by pulling the polyolefin foam base having a width of 1 cm at a tensile speed of 15 m/min to tear the foam base in a thickness direction of the polyolefin foam base such that the maximum strength occurs when the foam base is torn.
