In a formwork device for a shaped PC member, a metal lath waste formwork is placed as an inner formwork at the position of the cast-in-place concrete pouring surface on the side piece of the same member, and concrete is poured into the formwork configured in this way. After the poured concrete hardens, it is removed from the mold and an L-shaped PC member that also serves as a formwork is formed, so that the metal lath is anchored to the joint surface of the side piece of the PC member with the cast-in-place concrete. becomes.
