Medical pressure-sensitive adhesive sheet and method for producing the same

A medical pressure-sensitive adhesive sheet comprising a urethane substrate, an interlayer adhesive layer, an olefin nonwoven fabric, and a pressure-sensitive adhesive layer for pasting in order and having a moisture permeability amount of 2000 g/(m2·24 hours) or more,

• wherein a thickness of the urethane substrate is a value within the range of from 1 to 10 μm,
• the interlayer adhesive layer is a urethane-based adhesive layer, a thickness of the interlayer adhesive layer is a value within the range of from 5 to 30 μm,
• the olefin nonwoven fabric is constituted with a polypropylene-based thermoplastic elastomer and has a maximum point elongation percentage of a value of 200% or more in a longitudinal direction and a transverse direction, respectively,
• a content of the polypropylene-based thermoplastic elastomer contained in the olefin nonwoven fabric is a value of above 95% by weight with respect to a total amount of raw materials of the olefin nonwoven fabric,
• an MFR of the polypropylene-based thermoplastic elastomer contained in the olefin nonwoven fabric is a value within the range of from 1 to 48 g/10 minutes (temperature:
• 230° C.), and
• a thickness of the pressure-sensitive adhesive layer for pasting is a value within the range of from 5 to 45 μm.
