To provide a vehicle seat member in which polyurethane foam is stacked and bonded on a core material formed from thermoplastic resin foam, the vehicle seat member being excellent in strength and rigidity of the core material and also excellent in bondability between the core material and the polyurethane foam.SOLUTION: A vehicle seat member according to the present invention comprises: a core material formed from a thermoplastic resin foam body, and polyurethane foam stacked and glued on the upper surface of the core material. At least part of the upper surface of the thermoplastic resin foam body is formed from an upper surface of foam-particle molding composed of foam particle groups containing foam particles having bondable modified resin on the surfaces thereof. The foam particles having the bondable modified resin on the surfaces thereof are exposed from the upper surface of the foam particle molding. Each foam particle is composed of polyolefin resin (A2), and the bondable modified resin is composed of a mixed resin of polyolefin resin (A1) and polystyrene resin and/or polyester resin (B).SELECTED DRAWING: None

    【課題】 本発明は、熱可塑性樹脂発泡体からなる芯材にポリウレタンフォームを積層接着した車両用シート部材において、芯材の強度や剛性に優れ、芯材とポリウレタンフォームとの接合性に優れる車両用シート部材を提供することを課題とする。【解決手段】 本発明の車両用シート部材は、熱可塑性樹脂発泡体からなる芯材と、芯材の上面に積層接着されているポリウレタンフォームとからなり、熱可塑性樹脂発泡体の上面の少なくとも一部が、接着性改質樹脂を表面に有する発泡粒子を含む発泡粒子群から構成される発泡粒子成形体の上面からなり、発泡粒子成形体の上面に、接着性改質樹脂を表面に有する発泡粒子が露出しており、発泡粒子がポリオレフィン系樹脂(A2)から構成され、該接着性改質樹脂が、ポリオレフィン系樹脂(A1)と、ポリスチレン系樹脂及び/又はポリエステル系樹脂(B)との混合樹脂から構成されている。【選択図】 なし
