An airbag cover is provided with a linear laser cut groove constructed of holes having a depth within the range of the depth of the airbag cover so as to extend discontinuously and a recess thinned in the direction of the thickness at the end area of the laser cut groove. A recess extends in the direction along an extension L of the laser cut groove from the end of the laser cut groove and is provided with a first recess which is reduced in depth in the direction of the thickness (depth of thinning) as it gets closer to an end.
