PURPOSE: To obtain a lightweight and non-bulky web excellent in moisture-permeating and waterproofing properties, and having a sufficient heat-insulating property by covering a web with a porous resin layer consisting mainly of a polyurethane resin and containing a specific inorganic fine powdery material and specific fine particles.

CONSTITUTION: The characteristic of this web comprises containing (A) an inorganic fine powdery material having an average particle diameter of ≤1μm and having an N,N-dimethylformaldehyde-adsorbing volume of ≥200ml/100g in an amount of ≤1wt.% and (B) fine particles having an average particle diameter of ≤1μm and having a light-absorbing and heat-converting ability in an amount of ≥1wt.% in a porous resin layer consisting mainly of a polyurethane resin, wherein the total amount of both the components A and B is 2-40wt.%. The component B comprises at least one kind of (a) the carbide of the IV group transition metal in the periodic table, (b) stannic oxide doped with antimony oxide, and (c) an inorganic substance coated with the stannic oxide doped with the antimony oxide. Thus, the web having a moisture permeability of ≥7,000g/m2.24hrs and a water-resisting pressure of ≥0.6kgf/cm2, and good in the abrasion resistance and peeling resistance of the resin layer is obtained.
