Abstract: The flame-retardant leather-like sheet substrate of the present invention comprises a layer (A) that is made of an entangled nonwoven fabric comprising a polyester superfine fiber (a) of a single fiber fineness of 0.5 dtex or less containing no flame-retardant component and a flame-retardant polyester superfine fiber (b) of a single fiber fineness of 0.5 dtex or less containing a flame-retardant component in a ratio, (a)/(b), of 100/0 to 40/60 by mass, and a layer (B) that is made of an entangled nonwoven fabric comprising the polyester superfine fiber (a) and the flame-retardant polyester superfine fiber (b) in a ratio, (a)/(b), of 70/30 to 0/100 by mass. The entangled nonwoven fabrics of the layers (A) and (B) are impregnated with an elastomeric polymer (c) containing a flame-retardant component. The ratio of the polyester superfine fiber (a) and the flame-retardant polyester superfine fiber (b) in the flame-retardant leather-like sheet substrate is 10:90 to 90:10 by mass. The flame-retardant leather-like sheet substrate and the artificial leather made thereof have an excellent flame retardancy, a soft and high-quality feeling and appearance, a high abrasion resistance and peel strength, and excellent mechanical properties such as surface strength.
