To improve surface property on the mold frame surface side of a precast concrete panel, and to inexpensively produce the panel at low cost.
Reinforcing bars 3, 4 crossed and assembled are hoisted with a reinforcing metal fixture 2 having a suspending portion 2a obtained by bending the reinforcement into a U shape and also having a suspending portion of the reinforcing bars 2b obtained by bending the tip end of the respective suspending portions 2a at a right angle. Then, the position in the height direction within the mold frame is adjusted to provide the covering depth of the reinforcing bars 3 and concrete is placed, while holding that position. Thus, the precast concrete panel 1 having the surface 1a on the mold frame bottom face side made of concrete is formed, so that the the reinforcing metal fixtures 2 are exposed in the surface 1c on the mold frame upper side.
