PROBLEM TO BE SOLVED: To provide a patch for body surface excellent in adhesion and followingness to the skin, manifesting an appropriate stickiness in application and free from skin stimulation, troubles of odor, and to provide a method for producing the same. SOLUTION: The invention relates to the patch for body surface comprising a base and an adhesive layer formed on at least one face of the base and composed of a silicone based polymer and an emulsion polymerized acrylic polymer. Preferably, the adhesive layer contains the silicone based polymer and the emulsion polymerized acrylic polymer in a weight ratio of the silicone based polymer/the emulsion polymerized acrylic polymer=99/1 to 67/33. The emulsion-polymerized acrylic polymer preferably comprises at least one polymer of (meth)acrylates having a 4-12C alkyl group. The method for producing the patch comprises processes coating a mixture of the silicone based polymer and the emulsion polymerized acrylic polymer, curing the silicone based polymer and then vaporizing the water in the emulsion polymerized acrylic polymer to form the adhesive layer on the base.
