The present invention provides a vehicle interior material which is reliably cut when an airbag is opened. The vehicle interior material comprises: a basic material unit forming a frame of a vehicle interior material; a skin unit made of leather wrapped on the basic material unit; and a cushion unit inserted between the basic material unit and the skin unit. The skin unit is formed with a skin weak part along a virtual cutting line which is cut when the airbag is opened. The skin unit can have a curve in which a transition region from the skin weak part to a skin non-weak part is discontinuously raised or lowered.
