PURPOSE:To easily discard only the formwork having a stone masonry pattern from concrete placed by a method in which projections to be temporarily attached to the small holes of concrete panels are provided on the back side of a formwork having a stone masonry pattern which is to be provided to the surface of concrete placed. CONSTITUTION:In a concrete formwork 1 made of an expanded synthetic resin, having recessions 2 and flat joints 3 higher than the recessions 2 for providing a stone masonry pattern for the surface of concrete placed, projections 7 provided to the back side of the formwork 1 are temporarily attached to the small holes 10 of concrete panels 8, and concrete 15 is placed into the aperture between the concrete panels 8' facing each other. After the concrete hardens, the projections 7 are pulled out, the concrete panels 8 and 8' and the formwork 1 are disassembled, and the concrete 15 having a stone masonry-patterned surface is formed.
