An airbag includes: a base chamber; a left-half airbag inflated on a front-left side of the passenger, wherein a first opening is formed through the left-half airbag at an upper portion thereof; and a right-half airbag inflated on a front-right side of the passenger, wherein a first opening is formed through the right-half airbag at an upper portion thereof. A recess is formed between the left-half airbag and the right-half airbag so as to face the passenger, when the airbag is inflated in front of the passenger. The first openings are communicated with each other. A first seam joining the left-half airbag and the right-half airbag is formed to surround the first openings. The first openings communicated with each other are formed to extend in a vehicle front-rear direction.
