PROBLEM TO BE SOLVED: To provide an internal corner structure which exhibits excellent appearance without damaging natural taste thereof, and to provide imitation stones fitted for formation of the internal corner structure. SOLUTION: According to the internal corner structure, a butt end 11e of the first imitation stone 11 is abutted on one end a of the second imitation stone 12. A portion of the one end a of the second imitation stone 12, along a peripheral edge e thereof forms a flat portion b, and a portion of the same, separate from the peripheral edge e forms a non-projection portion c. The butt end 11e of the first imitation stone 11 abuts on the flat portion b almost without a gap therebetween, and therefore infiltration of rainwater etc. or see-through appearance of a substrate siding does not occur. A width of the flat portion b is preferably set to 0.5 to 1.0 times a value of T, and more preferably set to 0.6 to 0.9 times the value. The imitation stones are used not only in the internal corner but also in the periphery of a sash. COPYRIGHT: (C)2005,JPO&NCIPI
