To provide an artificial leather capable of securing mechanical strength even when being highly filled with an additive that is solid at normal temperature.SOLUTION: An artificial leather has at least a layer made of synthetic resin and a fiber fabric substrate. The layer made of synthetic resin consists of three or more layers, and a skin layer, a reinforcement layer, an adhesion layer are stacked in this order from front side. The skin layer and the adhesion layer contain additive that is solid at normal temperature. Containing rate of the additive that is solid in normal temperature is lower at the reinforcement layer than that of the additive that is solid in normal temperature in the adhesion layer.SELECTED DRAWING: Figure 1 【課題】常温で固体の添加剤を高充填する場合であっても機械的強度が担保できる合成皮革を提供すること。【解決手段】少なくとも合成樹脂からなる層と繊維布帛基材とを有してなる合成皮革であって、合成樹脂からなる層は３層以上から構成され、表面側から表皮層、補強層、接着層の順で積層されるものであり、表皮層および接着層は常温で固体の添加剤を含有してなり、補強層における常温で固体の添加剤の含有割合が表皮層および接着層における常温で固体の添加剤の含有割合よりも小さい合成皮革である。【選択図】図１
