Medical pressure-sensitive adhesive sheets having a pressure-sensitive adhesive layer on at least one side of a support so as to have an appropriate tack strength and acceptable processability. The pressure-sensitive adhesive layer is formed with a pressure-sensitive adhesive composed mainly of an acrylic polymer and a compatible component that is compatible with the acrylic polymer. The support layer contains a compatible component that is compatible with the acrylic polymer. The amount of the compatible component contained in the support layer is 70% or less of the amount of the compatible component contained in the pressure-sensitive adhesive layer and the support layer has an elongation of 200% or more without containing any compatible component.
