Vehicle interior material

A vehicle interior material having a multilayer structure, the material consisting of:

• a hard core layer having a hollow portion inside;
• a design layer provided on one surface side of the core layer, the design layer located on an interior side of a vehicle;
• a first film layer provided between the core layer and the design layer, the first film layer being a first non-apertured film comprising a resin film material or elastomer film material and having a first tensile-compressive rigidity;
• and
• a second film layer provided on a surface of the core layer on a side opposite to the first film layer, the second film layer being a second non-apertured film comprising a resin film material or elastomer film material and having a second tensile-compressive rigidity that is lower than the first tensile-compressive rigidity,
• wherein a strain εa is smaller than a strain εb, the strain εa being a strain on a surface of a structure on a side of the first film layer, the structure consisting of the first film layer, the core layer, and the second film layer, and the strain εb being a strain on a surface of the structure on a side of the second film layer,
• wherein a thickness h of the structure is less than 20 mm, and
• wherein a relationship among the strain εa, the strain εb, and the thickness h of the structure satisfies the expression 0<εa×h/(εa+εb)<5.
