A seat structure member includes a cover and a seat pad. The cover and the seat pad are integrated when the seat pad is foam molded. A recessed portion is formed on a portion of a surface of the seat pad that is covered by the cover. Integrated molding of the seat pad and the cover is avoided at a location of the recessed portion, and a space of the recessed portion is formed between the seat pad and the cover.
