An airbag device for pedestrian is structured to inflate plural airbags side by side to suppress the impact to the pedestrian hit by the automobile at the area around the abutment portion between the adjacent airbags. An airbag 5L inflates to cover left half side of a rear edge portion of a hood 3, a cowl top 2 and a windshield 6 from the center of the automobile in a width direction, and an airbag 5R inflates to cover right half side. In the inflation state, the airbags 5L and 5R are brought into abutment around the center of the automobile in the width direction. Recess portions 10F and 10R are formed as cut portions of a front wall portion 8b and a rear wall portion 8c of an airbag storage case 8 from upper edge portions below the abutment portion between the airbags 5L and 5R.
