  "textContent": "A vehicle interior material is capable of preventing wrinkles from being generated on a design surface even when the material is heat-molded into a predetermined uneven shape while maintaining a low weight and high rigidity. The vehicle interior material of the present invention has a multilayer structure, the material including: a hard core layer having a hollow portion inside; a design layer provided on one surface side of the core layer; a first film layer provided between the core layer and the design layer; and a second film layer provided on a surface of the core layer on a side opposite to the first film layer, wherein a strain εa is smaller than a strain εb, the strain εa being a strain on a surface 31 of a structure 60 on a side of the first film layer, the structure 60 having the first film layer, the core layer, and the second film layer, and the strain εb being a strain on a surface 42 of the structure on a side of the second film layer.",
