Abstract: A seat pad (10) having a loading surface (11). In the seat pad (10), a lateral slit portion (15), extending from the outside towards the inside of the seat pad (10) in a first lateral direction (B1) that is parallel to the loading surface (11), is formed. A longitudinal slit portion (15) is provided at an end portion of the lateral slit portion (15), in a second lateral direction (B2) that is orthogonal to the first lateral direction (B1) and that is parallel to the loading surface (11). The longitudinal slit portion (21) extends from the lateral slit portion (15) towards the loading surface (11) in a thickness direction (H) that is orthogonal to the loading surface (11).

Abstract: A foam molded body production device (20) including a plurality of molds (21); a cavity (23) that is delimited, between the plurality of molds (21), by cavity surfaces (22) of the plurality of molds (21); and a protrusion portion (28) that is formed on the cavity surfaces (22). The protrusion portion (28) is formed from an elastic body. The cavity surfaces (22) are provided with a holding portion (29) that contacts a tip of the protrusion portion (28) when the plurality of molds (21) are closed, and causes the protrusion portion (28) to elastically deform inside the cavity (23).
