Claim Text:
1. An exterior structure, comprising: a building structure having an exterior wall of a building; an insulating member disposed on an exterior side of the building structure; a plurality of support elements disposed on the exterior side of the building structure; a plurality of quadrilateral facade boards disposed on the exterior side of the building structure, further outwardly than the insulating member and the support elements, and attached to the support elements so as to be adjacent to each other in a horizontal direction and a vertical direction, the facade boards covering the building structure, the insulating member, and the support elements; a front-side lateral joint portion disposed at a horizontal edge portion of each facade board, the front-side lateral joint portion being set back from a back surface of the facade board toward a front surface of the facade board and extending in the vertical direction; a back-side lateral joint portion disposed at another horizontal edge portion of each facade board, the back-side lateral joint portion being set back from the front surface of the facade board toward the back surface of the facade board and extending in the vertical direction; a front-side vertical joint portion disposed at a lower edge portion of each facade board, the front-side vertical joint portion being set back from the back surface of the facade board toward the front surface of the facade board and extending in the horizontal direction; a back-side vertical joint portion disposed at an upper edge portion of each facade board, the back-side vertical joint portion being set back from the front surface of the facade board toward the back surface of the facade board and extending in the horizontal direction; a lateral joint formed between each horizontally adjacent pair of the facade boards as a result of the front-side lateral joint portion of a first facade board of the horizontally adjacent pair of the facade boards and the back-side lateral joint portion of a second facade board of the horizontally adjacent pair of the facade boards being superposed; and a vertical joint formed between each vertically adjacent pair of the facade boards as a result of the front-side vertical joint portion of a first facade board of the vertically adjacent pair of the facade boards and the back-side vertical joint portion of a second facade board of the vertically adjacent pair of the facade boards being superposed, wherein, in at least four horizontally and vertically adjacent facade boards, the lateral joints form a joint area substantially linearly continuous in the vertical direction.
