<p>Provided are: a porous body having polymethyl methacrylate as the main component, which has continuous pores, 0.001 µm to 500 µm pore diameters for the continuous pores, and 10% to 80% for the percent open area of at least one surface; a separating membrane obtained from the porous body; an adsorbent obtained from the porous body; and a method for producing the porous body. With the invention, a porous body with the percent surface open area and pore diameter restricted to specific ranges can be obtained. Because this porous body has an ultrafine homogeneous porous structure with pore diameter that can be restricted to a range on the order of nanometers to micrometers, it can be used advantageously as a separating membrane or adsorbent, such as a blood component-separating membrane in an artificial kidney, etc.</p> |
