Low-temperature specific heat of heavily overdoped Bi2Sr2CuO6 single crystals was studied. The specific heat under zero magnetic field included a linear-T term, suggesting the presence of a large pair-breaking effect, which we attribute to impurities because their influence on d-wave superconductors increases when the energy gap decreases with carrier overdoping. The field dependence of the electronic specific heat followed well the prediction for an impure d-wave superconductor.
