To provide a pedestrian protection airbag device which can achieve stability of behavior of an airbag when the airbag is inflated and deployed.SOLUTION: A pedestrian protection airbag device 1 according to one embodiment of the invention includes: an airbag 5 which is released from a space between a hood 2 and a windshield 3 disposed at a front side of a vehicle to an outside of the vehicle and covers a pair of front pillars 4 disposed at left and right sides of the vehicle; and a cylindrical guide tube 6 which is disposed so as to enclose a center part 51 of the airbag 5 when the airbag 5 is inflated and deployed. The guide tube 6 has a rupture planned part 61 which is ruptured by predetermined tensile force and temporarily restrains inflation and deployment of the center part 51 of the airbag 5 by the guide tube 6.SELECTED DRAWING: Figure 2
