dc.descriptionWe study possibility of observing the process $h^{0} \to τ^{\pm} μ^{\mp}$ at a linear collider. The branching ratio is constrained to be of the order of $10^{-4}$ by the $τ^{-} \to μ^{-} η$ result. Supersymmetric standard models can reproduce such amount of the branching ratio by taking a specific parameter set. The Higgsstrahlung process $e^{+}e^{-} \to Zh^{0}$ is preferable because of its simple kinematic structure, then, the signal process is $e^{+} e^{-} \to Z h^{0} \to Z τ^{\pm} μ^{\mp}$. The most serious background comes from the process, $e^{+} e^{-} \to Zh^{0} \to Zτ^{\pm} τ^{\mp} \to τ^{\pm} μ^{\mp} ν\barν$. We estimate the significance of the signal, taking into account the background reduction.
