Vehicle door and manufacturing method of vehicle door

A door for a vehicle comprises an outer panel and an inner panel joined to the outer panel by an adhesive. An outer surface of the inner panel includes an outer surface main part crossing a bonding direction of the inner panel and the outer panel at a first crossing angle, and an outer surface inclined part connected to the outer surface main part via a corner portion so as to form a ridge line and crossing the bonding direction at a second crossing angle smaller than the first crossing angle. A part of the corner portion having the adhesive deposited thereon is provided with a recess and a pair of first ribs are formed in a part of the outer surface main part adjacent to the corner portion in a mutually spaced apart relationship on either side of the recess, the first ribs being inclined such that a spacing between the first ribs becomes smaller toward the corner portion.
