This laminate for adhesion to a living body comprises a pressure sensitive adhesive layer which is for adhesion to a living body and contains a carboxylic ester a base material layer which is positioned on one side of the pressure sensitive adhesive layer in the thickness direction and which supports the pressure sensitive adhesive layer and a barrier layer which is interposed between the pressure sensitive adhesive layer and the base material layer. The difference between the SP value (SPcarboxylate) of the carboxylic ester and the SP value (SPbarrier) of the barrier layer has an absolute value (SPcarboxylate-SPbarrier) of greater than or equal to 1.生物體貼附用積層體具備含有羧酸酯且用以貼附於生物體之感壓接著劑層、配置於感壓接著劑層之厚度方向一側且支持感壓接著劑層之基材層、及介存於感壓接著劑層及基材層之間之障壁層。羧酸酯之SP值(SPcarboxylate)與障壁層之SP值(SPbarrier)之差之絕對值(SPcarboxylate-SPbarrier)為1以上。1‧‧‧生物體貼附用積層體2‧‧‧感壓接著劑層3‧‧‧基材層4‧‧‧剝離層5‧‧‧背襯膜6‧‧‧障壁層
