摘要： Disclosed is a double-coated pressure-sensitive adhesive sheet adopted to fix a hard disk drive component, which includes a pressure-sensitive adhesive unit including a plastic film base having a thickness of 20 μm or less and pressure-sensitive adhesive layers arranged on or above both sides of the plastic film base; and non-silicone release liners arranged on both surfaces of the pressure-sensitive adhesive unit. The pressure-sensitive adhesive unit has a thickness of 60 μm or less, and the double-coated pressure-sensitive adhesive sheet shows an outgassing of 1 μg/cm2 or less when the double-coated pressure-sensitive adhesive sheet is heated at a temperature of 120° C. for 10 minutes. The double-coated pressure-sensitive adhesive sheet is free from silicone, thereby causes less contamination, evolves less outgas, and is superior in workability. It has further improved followability to difference in level by controlling the thickness of the plastic film base to 13 μm or less. Additionally, it becomes resistant to “lifting” from an adherend even when subjected to a heating process after affixation, by specifying the gel fraction of the pressure-sensitive adhesive layer within a range of 10% to 60%.
