PEDESTRIAN PROTECTION AIRBAG AND PEDESTRIAN AIRBAG DEVICE

A pedestrian protection airbag is formed in a bag-shape. The pedestrian protection airbag is stored in a folded state in a case which has an opening and is disposed in a vicinity of a rear end of a vehicle hood panel. The pedestrian protection airbag protrudes from the opening due to inflow of an inflation fluid to cover an upper surface of a front pillar. The pedestrian protection airbag has an outer peripheral sewn portion in which a plurality of panels are sewn together in a state where an inflow port into which the inflation fluid is allowed to flow is formed. The outer peripheral sewn portion has a general sewn portion, and a fragile sewn portion that is more easily broken than the general sewn portion.
