Provided is a vehicular door including a load transfer member. The load transfer member includes a transfer member body disposed in a wide-thickness portion in a door body, and a projection projecting downward from the transfer member body. The transfer member body has a lower region whose surface on a door-outer-panel side abuts on, or comes close to, the inner surface of the door outer panel, and an inclined region whose door-outer-panel side surface is inclined to come apart from the door outer panel and whose surface on a door-inner-panel side abuts on, or comes close to, the inner surface of the door inner panel. The thickness of the lower region and the inclined region in a door-thickness direction is set narrower than the width of an insertion portion between the door inner panel and a door beam.
