摘要： Provided are a pressure-sensitive adhesive composition that has a sufficient initial pressure-sensitive adhesive strength and can achieve both a resealing property and an easy unsealing property, and a pressure-sensitive adhesive tape using the pressure-sensitive adhesive composition. A hot-melt pressure-sensitive adhesive composition according to an embodiment of the present invention includes a styrene-based elastomer, an olefin-based elastomer, and a tackifier. The hot-melt pressure-sensitive adhesive composition includes 2 wt% to 80 wt% of the styrene-based elastomer, 2 wt% to 50 wt% of the olefin-based elastomer, and 2 wt% to 40 wt% of the tackifier.
