Abstract
Provided are a vehicular interior member manufacturing method and an airbag rupturing groove manufacturing method which can form an airbag rupturing groove excellent in invisibility even in a vehicular interior member having a hard substrate layer, while performing a proper control of the thickness of the remainder of the airbag rupturing groove to be formed. The vehicular interior member manufacturing method is characterized by protruding a metal blade having an edge flattened at least partially against a forming face of the rupturing groove, from a back side of the vehicular interior member and partially into the skin layer wherein a thickness of the skin layer into which the metal blade has not protruded corresponds to a remaining thickness of the skin layer, and confirming whether or not the metal blade is detected at a second detecting position while the metal blade is not detected at a first detecting position.
