    • PROBLEM TO BE SOLVED: To provide a thermoplastic resin foamed molded product excellent in rigidity.
      SOLUTION: The thermoplastic resin foamed molded product [1] includes at least three kinds of layers, that is, a skin layer, a low foam layer and a high foam layer in this order and is characterized in that the skin layer, the low foam layer and the high foam layer substantially comprise the same thermoplastic resin, the void ratio of the skin layer is below 1%, the void ratio of the low foam layer is 1-below 40% and the void ratio of the high foam layer is 40% or above. The laminate [2] is obtained by laminating the foamed molded product [1] on a base material. A laminate [3] is obtained by pasting up a skin material on the surface of the foamed molded product [1].
