PROBLEM TO BE SOLVED: To provide a corner substrate material which can be used for a corner where variously uneven surface-shaped substrate face crossing with each other and which can form a sharp fold at the corner on a finish coa. SOLUTION: A corner substrate material with an L-shaped section forming the substrate of the finish sheet is attached to a corner where a first substrate face to which an interior finish sheet is stuck and a second substrate face cross with each other, and provided with a pair of fixed piece extending along from the bend to the surface of the first substrate face and the second substrate face. A plurality of V-shaped incisions are formed at every distance and circular notches continuing to the V-shaped incision are formed between the adjacent fixed pieces. COPYRIGHT: (C)2004,JPO&NCIPI
