A level pointer for a ferroconcrete slab is provided to use to different kinds of reinforcing bars regardless of thickness by fixing a body to a vertical reinforcing bar using a slit and spiral part of a worm. A level pointer for a ferroconcrete slab comprises a body(10), and a band type fixing hole(20). The body has a vertical unit(11), a horizontal unit(12), and a pair of assembling holes. The vertical unit is contacted to one side of a vertical reinforcing bar(V). The horizontal unit is horizontally bent from an upper end of the vertical unit. The assembling holes are penetrated on the vertical unit. The band type fixing hole has a band(21), a housing(23), a worm(25), and a rotary handle(26). A center of the band is fixed to the body, wherein the plural slits are formed. The housing is fixed to one part of the band, and has a band inserting groove(24) wherein the band is inserted. The worm rotates in the housing, and has a spiral part which is meshed to the slits of the band. The rotary handle is assembled to one end of the worm at an outer part of the housing.
