Zusammenfassung:	The problem of the present invention is to provide a patch and a patch preparation having an adhesive layer with a high adhesive force, wherein the hydrophobic adhesive layer does not bloom even when an organic fluid component having high polarity is contained. A patch containing a support and an adhesive layer on at least one surface of the support, wherein the adhesive layer contains a synthetic rubber having a viscosity average molecular weight of 1,700,000 - 6,500,000, an organic fluid component having high polarity, a tackifier, and magnesium aluminometasilicate. In the patch preparation, the above-mentioned adhesive layer further contains a drug.
