The present invention provides means for improving bondability between a vehicle seat core and a cushion in a vehicle seat pad formed by integration of them without significantly impairing mechanical properties.A vehicle seat core (10) is characterized in that it is a vehicle seat core for forming a vehicle seat pad (1) by integration with a cushion (40), which comprises a foamed resin molded body (20) obtained by filling a cavity (101) of a mold (100) with a plurality of foamed resin particles (21) and performing in-mold foam molding, and that at least a partial region (20c) of a surface (20A) of the foamed resin molded body to which the cushion is bonded when forming the vehicle seat pad has a surface expansion rate of 40% to 85%, and the foamed resin molded body has a first fusion rate of 95% or more or a second fusion rate of 60% or more.
