A vehicle seat has a seat back which includes a seat cover that forms an outer surface of the seat, and an airbag that is held on a seat inner side of the seat cover. The airbag is deployed toward a seat occupant side while a burst portion formed at a sewn portion of the seat cover is released. In the burst portion, a first sewing line extending in a seat up-down direction and a second sewing line extending in a direction intersecting the first sewing line intersect with each other. Assuming that the seat cover portion around the burst portion is divided into a plurality of sections by the first sewing line and the second sewing line, a webbing cloth is provided for each section to regulate stretch of the seat cover in a planar direction when the airbag is deployed.
