A hybrid porous structured material may include a porous region and a non-porous region. The porous region may include an imaginary stacked structure, wherein a plurality of imaginary spherical bodies/cavities are stacked so as to contact each other in three-dimensional directions. The non-porous region fills the gaps between the imaginary spherical bodies. A spherical colloid particle is present in each of the plurality of imaginary spherical bodies in the porous region. A separation membrane may include the hybrid porous structured material. A water treatment device may include the membrane.
