1. A joint structure for a vehicle body member, the vehicle body member including at least two panel members, the at least two panel members constituting part of a vehicle body and being formed of a steel plate, the joint structure comprising:
spot-welds formed by spot-welding the at least two panel members to each other at a predetermined spot interval such that a predetermined clearance is formed between the at least two panel members; a plurality of laser-welds formed by laser-welding the at least two panel members to each other between the spot-welds such that each of the plurality of laser-welds and the spot-welds are not in direct contact with each other; and an electrodeposition coating film portion that covers a surface of each of the at least two panel members, at least part of the electrodeposition coating film portion filling the clearance, wherein the laser-welds and the spot-welds are arranged along the same straight line, the straight line intersecting a center of both the laser-welds and the spot-welds. |
