The magnetic phase diagram in a single crystal of copper metaborate CuB_2O_4in a magnetic field parallel to a tetragonal axis $c$ has been investigated. From the resonant, magnetic and magnetostrictive data the phase diagram ofCuB_2O_4 on a plane ``temperature - magnetic field'' is constructed. Themagnetic incommensurate-commensurate phase transition is caused by thesaturation of weak subsystem of copper ions in the strong magnetic field$H\|c$.
