Abstract
A synthetic leather has high flame retardance in addition to excellent mechanical strength and durability, which may yield a covered article having an excellent texture, and a covered article which has been covered with the synthetic leather. The covered article includes a synthetic leather and a covered article covered with the synthetic leather, the synthetic leather having a fiber base material layer including a non-woven fabric containing: 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 a thermoplastic fiber B having an LOI value, conforming to JIS K 7201-2 (2007), of 25 or more.
