To provide skin material for a vehicle interior in which generation of wrinkles on a surface of the skin material being suppressed and the skin material capable of covering a three-dimensional object in a state with an excellent appearance.SOLUTION: Skin material for a vehicle interior using natural leather or synthetic leather satisfies all the following conditions of: a shear stiffness value of 20[gf/(cm degree)] or more and 56[gf/(cm degree)] or less, flexural rigidity of 1.6[gf cm/cm] or more and 2.5[gf cm/cm] or less, and tensile strain of 7.5[%] or more and 10[%] or less. Thus, generation of wrinkles on a surface can be suppressed and a three-dimensional object can be covered in a state with an excellent appearance.SELECTED DRAWING: Figure 1
