PROBLEM TO BE SOLVED: To provide an exterior material forming an exterior cladding of a construction and a structure.SOLUTION: An exterior material A comprises: a decorative surface 7 on which multiple concave and convex parts are formed along a longitudinal direction; a metallic surface material 1a in which male-female connection structure is formed at upper and lower ends of the decorative surface 7; and a back face cover material 2, which is attached to cover a whole area of the concave and convex parts on the underside of the decorative surface 7 of the metallic surface material 1a. A surface material 1 and a back surface material 3 are integrated to form the exterior material A by filling a gap between the surface material 1, in which through-holes 19a are formed on a surface contacting a back surface of a concave part 7a of the back face cover material 2, and a back surface material 3, with a heat insulating material 4. |
