Zusammenfassung:	PROBLEM TO BE SOLVED: To provide synthetic leather including a foam layer formed by a dry method that may be manufactured by a method simpler than a conventional manufacture method without requiring a curing period.SOLUTION: Synthetic leather comprises at least a surface layer, a foam layer and a fibrous substrate. The foam layer is made of a urethane prepolymer having an isocyanate group at a terminal and including 2 to 6 wt.% of the isocyanate group. After applying the urethan prepolymer, 15 to 40% of the isocyanate group of the urethane prepolymer is reacted in a heating atmosphere, and the resultant is then adhered to the fibrous substrate, and thereafter, the rest of the isocyanate group is reacted to be cured in a humidified heating atmosphere.
