Disclosed is an adhesive skin patch having an SIS block copolymer as an adhesive component, which has an improved handling property and can reduce irritation to a user. The adhesive skin patch comprises a flexible substrate and an adhesive layer laminated on the substrate, wherein the adhesive layer comprises a styrene-isoprene-styrene block copolymer. In the adhesive skin patch, the tanH value of the adhesive agent as determined by measuring a dynamic viscoelasticity at 32‹C satisfies a requirement represented by the following formula 1 at at least one frequency laying between 0.04 to 0.25 Hz. 0.25x + 0.05 <= y <= 0.25x + 0.10 (formula 1) [wherein x represents a frequency (Hz); and y represents a tanH value]. ® KIPO & WIPO 2009
