To secure rigidity of a ceiling part of a door main body, while suppressing an appearance at the inside of a vehicle interior of a back door from being impaired.SOLUTION: A vehicular back door comprises a door main body (5) formed of an inner panel (10) made of resin and an outer panel (50) made of resin which are jointed to each other. An upper part of the outer panel forms a ceiling part (7) of the door main body and constitutes a spoiler part (56) protruding rearward. A service hole (26) open toward a front-side position of a lamp unit attachment part (58) provided at a rear end portion of the spoiler part and a plurality of support ribs (28) whose tips are in contact with or are adjacent to an upper portion of the outer panel are arranged at a portion where the ceiling part of the door main body is formed in the inner panel. The support ribs are formed to extend in a longitudinal direction and stride across the service hole. The service hole is blocked with a cover member (84).SELECTED DRAWING: Figure 4
