An exterior structure includes a front-side lateral joint portion and a back-side lateral joint portion disposed at horizontal edge portions of each facade board, a front-side vertical joint portion and a back-side vertical joint portion disposed at a lower edge portion and an upper edge portion of each facade board, a lateral joint formed between horizontally adjacent facade boards as a result of superposing the front-side lateral joint portion of one facade board and the back-side lateral joint portion of the other facade board one on the other, and a vertical joint formed between vertically adjacent facade boards as a result of superposing the front-side vertical joint portion of one facade board and the back-side vertical joint portion of the other facade board one on the other. In at least four horizontally and vertically adjacent facade boards, the lateral joints form a joint area substantially linearly continuous in the vertical direction.
