SOLUTION: On the exterior side surface of a backing material 4 molded into a panel of two kinds of lightweight concrete, a gigged cloth 6, a polymer cement mortar layer 8, and a finishing material 10 are arranged. The gigged cloth 6 is provided with gigged parts 6b on both of the front and back sides, and each of the gigged parts 6b is buried in the backing material 4 and the polymer cement mortar layer 8. The backing material 4 and the polymer cement mortar layer 8 are firmly integrated with each other via the gigged cloth 6. In the polymer cement layer 8, water absorption and shrinkage is very low and neutralization is hardly caused, so that the PC curtain wall with excellent durability can be provided.
