常、10〜500μの範囲にある。 In the sheet-like preparation obtained by this method, the micropores formed in the porous polymer layer are usually independent pores separated by partition walls with a thickness of 0.1 to 5 μm, and the pore diameter is 0.5 to 5 μm. It is about 10μ. In addition, since the porous polymer layer has a porosity of about 30 to 80%, it can contain up to about 70% by weight of the liquid active substance, but in practical terms, the maximum is about 50% by weight. is appropriate. Further, the thickness of the porous polymer layer is not limited in any way, but is usually in the range of 10 to 500μ.
