Beschreibung
Zusammenfassung:	Provided is a laminate having low air permeability and excellent moisture permeability in a low temperature and low humidity environment. The laminate is provided with a porous substrate and a moisture-permeable membrane disposed on one side of the porous substrate, the laminate having an air resistance of 3000 seconds/100 cc or greater based on the Gurley method according to JIS P8117-2009 and a first moisture permeability of 300 g/(m2·24h) or greater based on a moisture permeability testing method (the cup method) according to JIS Z0208-1976 under the conditions of a temperature of 5°C, a relative humidity of 45%, and a wind speed of 0.2 m/s or less.
