a door outer panel including
a projected section that is projected outward in a vehicle width direction,
a recessed section that is separated from the projected section and recessed inward in the vehicle width direction, and
a boundary section between the projected section and the recessed section; and

a panel reinforcement fixed to an inner surface in the vehicle width direction of the door outer panel, wherein
the panel reinforcement includes:
a first frame section that extends in a vehicle front-rear direction; and
a second frame section at a position that overlaps the boundary section in a vehicle side view and is configured to be able to transmit a load to the first frame section at a time when the load in an inward direction of the vehicle width direction is applied to the boundary section;

the second frame section includes:
a front-rear frame section at a height position of a door outer handle is provided, the front-rear frame section extending in the vehicle front-rear direction in a manner capable of transmitting the load;
an up-down frame section that couples the first frame section and the front-rear frame section in an up-down direction; and
a truss section that is configured in a truss shape by the front-rear frame section and the up-down frame section, an apex of the truss section being at a position that overlaps with the boundary section in the vehicle side view and on a vehicle front-rear imaginary line that connects a front end and a rear end of the door outer handle and extends to a front of a vehicle.
