Claim 0:
1. A synthetic leather comprising a fiber base material layer formed of a non-woven fabric sheet and a resin layer formed on the fiber base material layer, wherein the non-woven fabric sheet includes at least one flameproof layer formed of a web including a non-melting fiber A having a high-temperature shrinkage rate of 3% or less and a thermal conductivity, conforming to ISO22007-3 (2008), of 0.060 W/m·K or less and is formed by bonding the flameproof layer to a scrim layer including a thermoplastic fiber B having an Limiting Oxygen Index (LOI) value, conforming to JIS K 7201-2 (2007), of 25 or more, and wherein the non-melting fiber A is a flameproofed fiber or a meta-aramid-based fiber and the thermoplastic fiber B is a fiber formed of a resin selected from the group consisting of flame retardant liquid crystalline polyester, flame-retardant poly(alkylene terephthalate), flame-retardant poly(acrylonitrile butadiene styrene), flame-retardant polysulfone, poly(ether-ether-ketone), poly(ether-ketone-ketone), polyethersulfone, polyarylate, polyarylene sulfide, polyphenylsulfone, polyetherimide, polyamideimide, and mixtures thereof.
