摘要：
A weld-joining structure between an outer panel and an attachment is achieved, which is advantageous in terms of appearance, workability, and cost. To weld-join the outer panel and the attachments including, such as frame members and opening frames and opening frame members, which is a reinforcement or an interior or exterior member for use in the outer panel, the outer panel and the attachment placed on the outer panel are weld-joined by laser welding at overlapping portions of the outer panel and the attachment. The laser welding is performed along a polishing mark formed in one direction on an externally exposed-side surface of the outer panel and the attachment.
