A search for the pseudoscalar meson $\eta_b$ is performed in two-photon interactions at LEP2. The data sample corresponds to a total integrated luminosity of 610 pb$^{-1}$ collected at centre-of-mass energies from 183 GeV to 209 GeV. Preliminary results of the analysis in the $\eta_b$ mass region are presented. Several candidate events are found in different final states. These results are preliminary.
