The three-year Wilkinson Microwave Anisotropy Probe observations, combined with other cosmological observations from galaxy clustering and type Ia supernovae, favour a non-vanishing running of the primordial spectral index independent of the low cosmic microwave background multipoles. Motivated by this feature we study a cosmological constraint on the neutrino mass, which is strongly dependent on what prior we adopt for the spectral shape of primordial fluctuations, taking possible running into account. As a result we find a more stringent constraint on the sum of the three neutrino masses, mν<0.76 eV (2σ), compared with mν<0.90 eV (2σ) for the case where a power law prior is adopted for the primordial spectral shape.
