To provide a finishing stake system which can be used repeatedly while exhibiting a long lifetime and can be used readily even on a hard ground and in which a register mark can be positioned readily with respect to a pile and accurate positioning work is ensured through fine adjustment.

The finishing stake system comprises a pile member 10 formed into a straight rod which can be driven into the ground surface by any one material of metal or resin, a tubular section 21 being fitted to the outer circumference of the pile member 10 movably in the longitudinal direction thereof, a substantially rectangular planar register mark part 31 fixed to the tubular section 21 with one linear end crossing the axis thereof substantially perpendicularly and movable in the longitudinal direction of the pile member 10 through the tubular section 21, and an adjusting screw 23 screwed into the tubular section 21 and securing the register mark part 31 at a specified position in the longitudinal direction of the pile member 10 by fastening the tubular section 21 to the specified position in the longitudinal direction of the pile member 10.
