The resin molded article includes a main body part (20)·(21) configured to be mounted to a car body panel (26), a cantilever-shaped seal part (22)·(23) for sealing a gap in the car body panel (26), and a hollow tubular-shaped seal part (24). The seal part (22)·(23)·(24) is in resilient contact with the car body panel (26) in a state of being mounted to the car body panel (26). The seal part (22)·(23)·(24) is molded from a thermoplastic elastomer containing 25 wt% or more of an olefin block copolymer. It is preferable that the thermoplastic elastomer also contains a dynamically crosslinked olefin-based elastomer in addition to the olefin block copolymer.
