The magnetic phase diagram for antiferroquadrupole (AFQ) ordering in tetragonal $\mathrm{Ho}{\mathrm{B}}_{2}{\mathrm{C}}_{2}$ has been investigated by measurements of elastic constants ${C}_{11}$, ${C}_{44}$, and ${C}_{66}$ in fields along the basal $x\text{\ensuremath{-}}y$ plane as well as the principal [001]-axis. The hybrid magnet (GAMA) in Tsukuba Magnetic Laboratory was employed for high field measurements up to $30\phantom{\rule{0.3em}{0ex}}\mathrm{T}$. The AFQ phase is no longer observed above $26.3\phantom{\rule{0.3em}{0ex}}\mathrm{T}$ along the principal [001]-axis in contrast to the relatively small critical field of $3.9\phantom{\rule{0.3em}{0ex}}\mathrm{T}$ in fields applied along the basal [110]-axis. The quadrupolar intersite interaction of ${O}_{xy}$ and/or ${O}_{2}^{2}$ is consistent with the anisotropy in the magnetic phase diagram of the AFQ phase in $\mathrm{Ho}{\mathrm{B}}_{2}{\mathrm{C}}_{2}$.
