PROBLEM TO BE SOLVED: To provide a method for producing artificial leather provided with a pressed flower in the inner part having a freshness retention function in a vacuum. SOLUTION: The method for producing the artificial leather provided with the pressed flower in the inner part has a first step for feeding a raw material necessary for producing transparent artificial leather to a hopper, treating the raw material into a hot-melt state by a pretreatment mechanism having high pressure, electric heat and transmission shaft function and reducing the raw material to a liquid state by a screw extrusion mechanism, a second step for passing a substrate to which a dry flower is bonded and which has tension properties between cooling roll sets, forming a liquid retention section by dividing the cooling roll set at the dry flower end side, receiving the liquid raw material for the artificial leather flowed down in the first step by the liquid retention sections, sterilizing the dry flower on the substrate and the substrate at a high temperature by immersion by the liquid raw material, forming a coated film and pressing out and removing air at the coated substrate side, and a third step in which a liquid retention section is formed by dividing the dry flower end side of the substrate by another pair of the cooling roll set and a different liquid raw material for the artificial leather is retained in the liquid retention section, thus forming a coated film on the bottom of the substrate.
