PROBLEM TO BE SOLVED: To provide an air-bag door and an air-bag device which suppresses that a three-dimensional knit cushion layer is fractured at a portion different from a tear line while suppressing the deterioration of appearance under a high temperature.SOLUTION: An air-bag door 13 which constitutes a part of an air-bag device includes base material 15, a three-dimensional knit cushion layer 20 which is laminated on the surface of the base material 15 via an adhesive layer 40 and a skin 25 laminated on the surface of the three-dimensional knit cushion layer 20. On the base material 15 and the three-dimensional knit cushion layer 20, tear lines 16, 21 which become a starting point of fracture when being pressed by the air-bag which is developed and expanded are respectively formed. A specified region 40b which contains a portion formed by projecting the tear line 16 of the base material 15 and has a width wider than the tear line 16, of the adhesive layer 40 causes the three-dimensional knit cushion layer 20 to be adhered to the base material 15 with an adhesive force lower than that on an ordinary region 40a besides the specified region 40b. |
