PROBLEM TO BE SOLVED: To provide a seat for rolling stock excellent in recyclability and high in the degree of freedom in shape and structure and high in a product value by using a raw material for a lower seat layer which is easily moldable even if it is a large-size and thin molding. SOLUTION: After a molding body constituting a lower seat layer 2 is put in a mold, polyurethane raw liquid is injected in the mold and foamed to produce the seat 1 for a rolling stock in which an upper seat layer 3 made of a flexible polyurethane foam is integrally molded.
