PROBLEM TO BE SOLVED: To provide a trim object for a building which is rigid for less weight and allows screwing. SOLUTION: The trim object for a building is extrusion-molded with a fiber-reinforced hydraulic composition, and has such property as causes multiple cracks under a bending burden to break up. A reinforcing fiber selected from among a polypropylene fiber, a polyethylene fiber, and a polyvinyl alcohol fiber is mixed with a hydraulic cement matrix by 1-10% of voluminal entrainment rate.
